God did not create many religions. He is a God, not of disorder, but of peace.
Millions of people have died over the years because of man-made religion. None of those teachings came from God, but from the human need that some have to sin at the expense of others. But God points to a different view:
27 The form of worship (or, religion) that is clean and undefiled from the standpoint of our God and Father is this: to look after orphans and widows in their tribulation and to keep oneself without spot from the world.
John 8:31, 32
31 Then Jesus went on to say to the Jews who had believed him: “If you remain in my word, you are really my disciples, 32 and you will know the truth, and the truth will set you free.”
Matthew 15:8, 9
8 ‘This people honor me with their lips, but their hearts are far removed from me. 9 It is in vain that they keep worshipping me, for they teach commands of men as doctrines.’”
