I don't believe that all organic life is an ascendant of a previous less complex version of itself. Not only is there no concrete evidence to substantiate this claim, it's also next to impossible. The probability of evolving one molecule of iso 1 cytochrome c is one chance in 2.3 times ten billion vigintillion. Timewise, if a random mutation occured every second since the beginning of the Earth this molecule would only be only 40 or so percent close to completion. Keep in mind that this is one Molecule.

youre right...but thats the crux of the matter right there....
A. do you believe that just the right reactions happened at just the right moment...
or
B. you believe a Being somewhere created us out of thin-air

i dont know what to believe
and i think we'll never really have an answer to this question
