Man is the creation of man, both in the biblical and the biological sense.
The biblical in regards to our greatness. A greatness which is so great that, in fact, we have to conceptualize a God or superior being which has no legitimate evidence (apart from theoretical and idealogical texts) of its existence.
Man is God, and therefore man creates God, just as man creates man.
In biological terms, man creates man through simple fucking. Whether it be through lust, or lust and love, we create an offspring to kick off what we call the next generation of human - that is, the next generation human which is relevant to our time of existence. And so on and so forth.
In truth, if there is any meaning to life, it's to learn, develop oneself, and to create. Whether it be through love making, solving a mathematical equation using creative original methods which have been spawned from derivatives created by other mathematicians, or simply exercising one's brain and physique and establishing ones own rules and ethics in order to improve thyself, man's potential lies within man itself.
Man is the general conception of the human being. Male and female, or female or male; it doesn't matter.
For thousands of years man has evolved and developed through the creation of solid objects, fundamentals which have lead to concepts, ideals, and breeding.
We have invented languages; given meaning to our own morals, existences and the items which we take under our wings as ownerships; and discovered the unknown by setting forth to conquer to and to achieve.
"Not because they are easy, but because they are hard."
We are the representation of the perfect being. So perfect, that we have to think of perfect as a complete step up far and beyond our own expectations, which we invent ourselves (the irony is that this perfection can be achieved, because we can conceive of it and understand it). We even invent the concept of conscience, or thought.
These simple things are what carve dirt roads on the pathways, only to be paved by cement and thus studied in order to create more resourceful and effective materials to cover with once more. That is evolution; we define evolution in simple day-to-day life. It's the highest form of comprehension.
What lies beyond that? We do not know, nor can we comprehend. We're simply not ready for that...yet.
