When was the start of everything?

The most popular view among the present day scientists is that the universe and alongwith it time was created with a Big Bang about 13.4 billion years ago. This theory rests on astronomical observations of color patterns of stars, on the background radiation between stars, and the scattering of various elements in the universe. It is however possible that the color patterns are not solely dependent on physical movement based on which the figures have been arrived at. The patterns of color might have changed partially or even entirely due to loss of energy of light with time.
It is therefore quite difficult to ascertain the beginning of time because it had been almost impossible to distiguish among “Big Bang”, “Tired Light” and “Dissipative” models. It is quite possible, in that case that time has no true beginning. It is best to keep an open mind on this subject for the present.
One down to earth estmate says that our biological time began about 4 billion years ago with the appearance of permanent liquid water on earth.

I shall now report a few details of the research by Stephen Hawking who said “God not only plays dice. He also sometimes throws the dice where they cannot be seen.”

Hawking's had researched  the concept of singularities (the most important example of a singularity is a black hole, the final form of a collapsed star) break downs in space and time where the classic laws of physics  are no longer applicable. Space-time is the combination  of time and three dimensional space.
In late 1960s Hawking established that if GTR was correct then it was at the big bang that a singularity had occurred. The start of the universe and time-space coincided with the big bang. The cosmic clock came into existence then only. His research in space and time sometimes blurred the thick line between science and philosophy. That was why he said: “Even if there is only one possible unified theory, it is just a set of rules and equations. What is it that breathes fire into the equations and makes a universe for them to describe? Why does the universe go to all the bother of existing? Is the unified theory so compelling that it brings about its own existence? Or does it need a creator, and if so, does he have any other effect on the universe? And who created him?”
Stephen Hawking believd that the reason we came to the Earth was to find the reason for our existence in this planet, or of any existence at all.

I have a problem with big numbers. It sems to me that if there are billions of people on this planet, then the likes of Hitler or Ghandi are bound to occur. There power for good or evil are tempered by the support they get.
In a infinite universe, or an extraordinarily big one, I fail to see how we should speculate on a beginning. Of course we can say we believe ( or not ) in a big bang, but who is arrogant enough to claim Knowledge beyond what we can measure? How many times will man claim answers he does not have? Is not our current Environmental troubles entirely the fault of previous so called knowledge.
In a universe this big there is always a bigger picture.
