Yes I agree it is a very vast topic for a forum.
However on the chance and the probability thing, rare things do happen, the very fact you are born is nearly impossible, In each human coupling, a thousand million sperm vie for a single egg. Multiply those odds by countless generations, against the odds of your ancestors being alive, meeting, and then having you, well theres more chance of the air your breathing right now turning into gold, and yet here you are typing away...
Is this only because of some god, well what is god? The fact of the matter is if you truely think about it we are infact god or in other words the universe, we are made up of the same star dust that was present in the big bang, so infact we made ourselves... We eat cows or animals however in 3000 years time when we are dead and decompose and turn into soil we will be eaten by these very animals if not some evolved version..
Every thing is inter-linked there is no sepearate being which created everything, we are part of a system and infact are the system at the same time.. bit of a paradox really.
That has to be some EPIC weed you've got there...
