You atheists do not believe in God, but believe that all life evolved from single-celled organisms. You cannot prove this as fact with your scientific methodology thus you are accepting the premise on FAITH.

Seems you've led a sheltered life and only been exposed to the modern Americal style of fundamentalist religion!? Just my two-penneth.
