If 'God' is the Christian god from Bible, then why did he even create all those other religions like Hinduism anyway?
Just to send all those people to Hell? Yes and I don't understand the natural disasters which he started himself
He didn't. This silly Western idea that God does everything goes against the original Christian Church (Orthodox). The difference between Churches is that the West 'revolutionise' while the Orthodox Church is fundamentally unchanged from the period of Early Christianity.
Man is a flawed entity, a splitting of our human and divine natures that occured when Adam bit the apple. As a result, we are unable to participate in God, without becoming like Christ, who was perfectly, equally, and inseperably both human and divine.
Without Christianity, it is much harder to become what we originally were, holy.
If that didn't make sense, then welcome to the wonderful world of theology. I'm simplifying, it has better parts about why Jews look funny and why we should all be communists.
