I was reading on Samaritans, Pharisees, seducees beliefs, what if that religion was something people were building on top

For example why did God create Adam and Eve Sexual reproduction in this world, but excepts in on the new world. Wouldn't it be cool if paradise was built on innocence, purity and love. That you can only have one partner for sex in afterlife but this raises question how will we supreme being judge people.
