Questions by a fellow atheist

How do you justify your existence?
I am wondering how many of you out there wonder about your existence? What on earth are you doing here?

I always get amazed when I think about the complexity of the life forms....for instance...all complex life forms have almost perfect design for seeing things around - eyes? similarly for hearing?...for that matter any part of the body......and humans have outclassed other species with...complex network of neurons...which helps them to think ahead in future!!

And more amazing is the fact that all these evolution occured begining with random aggregation of molecules to start with and..life kicked itself into action....the aggregation that survived the hostile environment..what Darwin would say....'survival of fittest'....replicated further....and aggregated further...and continue to evolve.....over millions of years....to what we are today.....and so it continues....the battle of survival...which including humans inherently indulge in every day...as proved by the way humans would try to outclass/compete other peers, find a better mate, etc....

It appears all life forms are survival machines designed to take advantange of different environment/living conditions to do one thing best....survive!....ensure the propagation of their design....which is embedded in the genes!!

So what are we, biological survival machines - biological robots ??

WHAT I HAVE TO SAY ABOUT IT.
I have thought about it, and continue to think about it, futilely though, this is the biggest reason why humans thought of the concept of god in the past, currently people are too ignorant to question themselves. probably some day scientists will answer the question. hopefully in my lifetime.
