Can you prove to me without a doubt that we evolved from single-celled organisms? No, because it is not a testable theory.
The similarities between species today could be a result of
1) diverging species from a common ancestor or
2) intellegent design with common traits.
Yet the school systems teach evolution more as fact rather than an un-testable theory.
So who's putting up the smoke and mirrors again? I at least acknowledge that anything is possbile until proven false. Do you disagree?
