Mankind has developed over millions of years to arrive where we are today, and even now we are not yet at the pinnacle of evolution, if there can ever be such a thing.
We are evolving daily. Maybe not enough for us to see in our short lives and maybe not physically changing with each generation, but we are evolving ideas and technical abilities: new and truly wonderful tools which help us, force us even, to change and adapt in a pseudo evolutionary way.
Regardless of whether or not there is a God, simple human knowledge of self, rationality and emotions all contribute to our present revolutionary pace. And yet, we still need to answer the most fundamental question of where we come from with the idea of God. Perhaps we should try to look at the whole thing in a different way., and by doing so, understand how we could be manipulated because of these basic human traits.
On the face of it, historically, there does not seem to have been much of a challenge to these evolutionary oriented beliefs until the enlightened age of philosophy. This appears to be the time when man challenged all ideas, even his own. The early philosophers required their students to assume what they were being taught was wrong and to come up with their own ideas. Although man was challenging the assumptions of life long before the existence of the classical philosophers. However, apart from what can be learned from their buildings, new understanding can come from the early writings in which secrets have been locked away for thousands of years, only to be understood by those with the eyes to see

We can see from these writings and structures that man has understood, or found the need for, a clear beginning and end. A cycle of life emerged and with it came a religious copy of this cycle, more complex and intuitive than we could ever imagine. Recently emerging data has put the beginning of civilisation further back in time, and has proved that there was greater knowledge among early peoples. With every passing day we find new evidence for the purpose of megalithic structures. The secret resonance, the effects of radiation causing lights in the sky, the planetary alignments, Earth energies and pathways, the symbolism of life and death; all these things are coming under closer scrutiny and many are being proven.
The fact that our ancestors knew so much about the cycles of life is partly the cause of the problem of understanding our beginning. These ideas and beliefs in life cycles over many thousands of years and our own in-built cyclical nature will not allow us to comprehend anything without a start and finish.
