it took many many years to evolve from microscopic to our present selves. i coulnd't imagine an eyeball evolving over only a couple hundred generations? when our bodies first started developing eyeballs, i can't see them working for these first generations. why would our body keep evolving them over a long period of time. i can't see our body knowing that it would become an eye after a 1000 years. wouldn't our body have started to spit it out if it didn't work after a couple of generations?
