Sgt did you even read my posts? We didnt start as perfect. Our body adapted to our needs and evolved.

Strelok, ofcourse religion has been around for long, not forever
Someone had to come up with answers, and there wasnt enough technology to do it scientifically so some wack-job invented God.
Churches also used religion as a method to control people, read some books.
Look at the Greeks, the believed in tons of Gods, they were used as explanations for the things. We had enough sense to realize theyre fake.
