What would life be if we had no courage to attempt anything? -V VG

I was recently contemplating the meaning of life. I know that sounds excessive and dramatic but i was just pondering the question because there were children screaming around me and often people say; to have offspring is why we are here. I thought that if we looked at how other species live we could come up with a good reason why we are here. All other species, according to Darwin, and what seems to make the most obvious sense are regulated by survival of the fittest, where only fit individuals in life are able to reproduce and continue on. We work everyday and exercise and do things to make us happy, to ensure health, well being and survival in the most fulfilling way. Unfortunately most of the world isnt run on Social Darwinism which is often contradictory and exploits ideas of survival of the fittest. It commonly refers to notions of struggle for existence being used to justify social policies which show no sympathy for those unable to support themselves.
I think that when we were put here maybe it was thought that we'd always run at a reproduction level that could still be regulated by survival of the fittest, but unfortunately/(fortunately) our world caters to those who are sick, weak and anyone who is dependent on a drug or help etc etc. Its hard to accept SD as a way of living because a mother wont leave a child to die but in the animal world she often will in order to survive herself. (sad)
I was debating the over population of the earth with my collegues, i was arguing the theory around Social Darwinism and eugenics (selective breeding of humans) while they brought in the ethics and culture and all the other things that have changed the reason why society isnt solely run by survival of the fittest. They claimed society doesnt work that way and i disagreed by pointing out that men prefer women who show features of fertility and women those of men that project high levels of testostrone. Both in an attempt to mate with strong individuals, the men want a woman who can have many children and the woman wants children who will survive. Obvisouly social constructions and trends have ruined this by suggesting otherwise.
So the meaning to life may be to have children, but they are supposed to be good children who are the cream of the crop. However today our society will allow a person who has no home and no food to breed and somehow this child will still survive through donations and the support from society. I would never suggest we not help those in need but society, culture, ethics, medicine and the extreme advancements in comparative to chimps, that maybe our creator didnt think we'd accomplish, have made it difficult to answer the question as to why we are here.
