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).
