It started with a bang

The big bang! And after eons evolving here on Earth we find ourselves firmly ensconced within the cosmic cradle of space/time -- constrained by the one-way march of time, confined by physical limitations, and not really sure where we came from or where we are going.

Before the big bang there was neither space nor time, at least not as we now know them. Anyway that is what the best scientific minds tell us; fact is, we know nothing about the realm that preceded the big bang. However, with the big bang space opened, time flowed, and the evolution of complexity commenced. Immediately following the onset of the big bang, the process of evolution began its developmental activities by combining tiny particles of matter. Atoms merged with atoms and soon were forming molecules. The zeal of the evolutionary process to reach for increased complexity continued its march until molecules formed cells and in time these inanimate cells crossed the critical threshold to become tiny living entities.
