Really doesn't take that much for something simple and random to turn into something seemingly complex. The game of life is a good example of this, with just a few extremely simple rules allowing hugely complex, and seemingly 'alive' scenarios to unfold.
It certainly doesn't, because even if the chance is 1/15153th, it's been taking billions of years. even 1/100 000 000 000 can happen, and propably will in some span of time.
Seriously though, I would love if we would stop ridiculing creationsts and instead give them hard irrefutable arguments instead. I am propably one of the most hardcore evolutionists in this forum - even though I am nowhere as eloquent or elegant as aldo or Kara - but sometimes I think that groupthink and "LOL" arguments are too common.
Evolutionary theory is, by far, one of the best scientific hypothesises we have. There are more grounds for attacking gravity or general relativity or certain philosophic ideals or quantum theories than there are to attack evolution. Sarcasm, inside jokes and stuff like that is unneeded, because
A) evolution is very, very well proved
B) you can't really change mind in INTTERNET
Just simply refer to empirical proof. You'll find lots of it. Like, huge amounts. JUST LOOK AT THE FUKKEN MODERN MEDICINE YOU DUMB ****ES
