To get an answer of this question, first we need to understand how religions came into existence. Science has proved that our ancestors were related to apes and used to live on trees. Then they descended from trees and hunted animals and gathered food. Animal rearing and agriculture solved the problem of searching for food. Discovery of fire and wheel gave them an advantage over other animals. So, gradually their life became sedentary and their mental capacity increased. They started thinking about the world, its origin, and wonders of nature. They thought everything was caused by miracles. So, they started worshiping natural powers like Sun, moon, fire, water, storm, day, night, rain, strong animals, etc. They worshiped the mother goddess as woman give birth to children. Then they started worshiping female genitals and phallus (penis).
But, these mannerisms also changed. Later they imagined gods and goddess who had the same thinking and body structure as we have. They had powers of animals and could harm or do favor a person. Then they imagined a leader of gods who is known as Zeus in Greek mythology, Jupiter in Roman mythology, Amun-Ra in Egyptian mythology and Indra in Hindu mythology. Later people realized that there must be someone and something greater that these deities. So, they thought about a Supreme power, which is known as God, Bhagwan, Ishwar and Allah etc. in different parts of the world. That power is known as beyond human imagination, omniscient, omnipresent and omnipotent.

In every part of the world different methods of worshiping and religious faiths are found. People ask why there is not a single religion in this world. The reason is that in the ancient time travelling was very difficult. Civilizations were scattered in the very large part of the world. Means of communications were limited. So, every civilization developed its own distinct culture, art forms and religious beliefs. Thinking of every person is unique and they also have their own cultural and religious beliefs. Some wanted to be more devoted to religious beliefs while others had opposite thinking, some were superstitious while others were progressive. So, many complications started off on account of it. When someone felt that the old religious beliefs had become outdated, he started his own religion and when someone felt that people are not following the ‘true ancient religion’, also started preaching about it. So, all these factors originated many religions and religious beliefs.
When Mahavira saw that the ancient Vedic religion was spoiled by superstition and inhuman beliefs, he started preaching against it. Later, his followers become Jain. His contemporary Gautam Buddha also wanted people to think rationally. His followers become Buddhist. In China Confucius and Lao Tsū’s followers also become a distinct community and become different religions. Jesus preached against the vices of ancient Judaism. His followers become Christian. The same is true for Mohammed and Guru Nanak. So, we can see that whenever any person raised his voice against the vices of old religious beliefs, he gave birth to a new religion. So, we come to this conclusion that major changes and reforms in the old religion start a new religion. Al though it may not be known as a new religion at first, it becomes a new religion later. Religions also formed on account of people's ambitions and lust for power.
One can witness the ancient religious practices in tribal people, whose religious beliefs are mostly based on spirits, worshiping of various types of gods and goddesses, distinct rituals and superstitions. But, we should be careful to call them superstitious because more or less, every religion is based on superstition. Their stories are based on imaginations and instigate a sense of blind following, instead of rational thinking.
Man’s eternal faith cannot vary in step with time and place.
In truth, eternal faith is however one—not several.
But then, why are there really several religions?
Man in his pure state of consciousness has however one eternal faith. However, having become captive and conditioned by matter via the influence of the 3 modes of nature, man’s faith has diverged into two:
Temporary or sectarian.
Eternal or non-sectarian.
Non-sectarian eternal faith doesn't modification in step with time, place and folks. Whereas the conditioned living entities, having become captive and conditioned by matter, have developed numerous religions in step with the variations of your time, place and circumstances. As a result sectarian religions have accepted totally different designations and forms in several countries supported the bodies and bodily identification of the practitioners. As and once the conditioned soul becomes free from mundane identifications, therefore concomitantly his faith becomes non-sectarian. Liberated from all mundane identities man’s faith is one and eternal.
At the best levels of spiritual development there'll be very little bad blood or hostility between the followers of various religions, however lower down within the baser modes of passion and cognitive content the variations are irreconcilable . Our issues these days area unit because of the rise within the modes of passion and cognitive content that influence the center and lower tiers of spiritual individuals.
Humans had always been blessed with that freewill and right to believe whatever they want to believe. It is rather an unfortunate thing that humans too see things and understand things in different ways. This is the main reason why we see many religions in the world today. Because A believes this and B believes something else, B goes ahead to create a new group for those who share his idea and thought and it forms a new religion just like that.
So i will say the reason why we have so many religions today first comes from our differences in believes and how we see things and secondly, the freewill we have to choose whatever we want to believe. These are the two main reasons why we see so many religions in the world and even in thesame religion, we still have different sub-groups that have slightly conflicting believes again within thesame religion.
So you see how far this can continue to go...
The world is a big place and different people around the world need a means to explain things that can't be explained, hence the conception of religion. There are so many religions worldwide because there are so many cultures worldwide, each one have a different idea about who runs the world and how the world was created. If not for missionaries and jihads, then i wreckon there would be a religion for every state worldwide.
Answer: The existence of so many religions in the world and the claim that all religions lead to God are clearly confusing to many people, who earnestly seek the truth about God. Usually they feel desperate about the possibility of whether they can get absolute truth about the topic.
Finally, they embraced the universalist claim that all religions lead to God. Moreover, skeptics also use the fact that there are so many religions as evidence that humans cannot know God; or he doesn't exist at all.
Romans 1: 19-21 contains a biblical explanation of why there are so many religions. God's truth is seen and known by every human being because God made it so. Instead of accepting the truth about God and submitting to it, most people reject it and use their own ways to understand God.
But this does not lead to enlightenment about God, but to the futility of the mind. Here we get the basis of the emergence of "many religions."
Many people do not want to believe in God who demands truth and morality, so they create a god who does not demand such things.
Many people do not believe in God which states that it is impossible for someone to enter heaven in his own way. So, they created a god who accepted people into heaven if that person had completed certain steps, followed certain rules, and / or obeyed certain laws.
Many people do not want a relationship with a sovereign and almighty God. So, they imagine God more as a mystical force rather than a ruler who has personality and sovereignty.
The existence of so many religions is not a refutation of the existence of God. Or it is used as a pretext that the truth about God is unclear. On the contrary, the existence of so many religions is evidence of the rejection of mankind against the one true God.
Mankind has replaced Him with gods that are more in line with their tastes. This is a dangerous business. The desire to create god according to our own tastes, which is derived from the nature of sin in us - in the end will only "reap corruption" (Galatians 6: 7-8).
