Carl Sagan words : We humans appear on the cosmic calendar so recently that our recorded history occupies only the last few seconds of the last minute of December 31st .
In the vast ocean of time which this calendar represents all our memories are confirmed to this small square (the last day).
Every person we have ever heard of lived somewhere in there , all those kings and battles , migrations and inventions wars and loves .
Everything in the history books happens here , in the last 10 seconds of the cosmic calendar .
We on earth have just awakened to the great oceans of space and time from which we have emerged .
We are the legacy of 15 billion years of cosmic evolution .
We have a choice :
We can enhance life and come to know the universe that made us , or we can squander our 15 billion years heritage in meaningless self-destruction .
What happens in the first second of the next cosmic year depends on what we do , here and now with our intelligence and our knowledge of the cosmos .
Universe was created in BIG BANG , and it is transformed into building up of complex life as we know it today .
Did life was created in the beginning – was universe alive since its beginning ? Or else Life was created in the process of transformation .
Intelligent life was created on Earth , what was once a stardust has now been transformed into beings of this beautiful planet called Earth . Alien intervention can be a possible guess for injecting the seeds of life on Earth , perhaps creating a complex brain structure
We perhaps the most insignificant on the time scale of the universe and what we know is very little about our elegant universe .
