Is this part of the ultimate question... Who am I...Why am I here ?
What would you say if I was to tell you that there is no great mystery and it was all very biologically simple.
We, like all other animals on the face of the planet have a life cycle. As part of that cycle we as individuals strive to pass on our genes to the next generation. In some animal structures only the Alpha male and female are allowed to breed. In others the females chose with whom to breed after much demonstration of male superiority indicates to her which male will give her offspring the best chance of survival.
It used to be this simple in humans too. Until religion came along and religious leaders proclaimed that man was in some way superior to all other animals and they told us that the other animals were ours to use as we please, yeah even unto their extinction... such was the extent of man’s superiority.
Procreation for survival became Sex, sex became fun and.... well you can work out the rest for yourself. Suffice to say it became the total screwed up mess you see today.
