It is theorized that the true age of the earth is about 4.6 billion years old. Source
It's believed that humans originated about 200,000 years ago in the Middle Paleolithic period in southern Africa. By 70,000 years ago, humans
migrated out of Africa and began colonizing the entire planet. They spread to Eurasia and Oceania 40,000 years ago, and reached the Americas by 14,500
years ago. Source
As of 13 February 2010, the Earth's population is estimated by the United States Census Bureau to be 6,802,400,000.
Based on those theories, our existence is but a mere drop in the bucket.
So let’s do some math…
4,600,000,000 (earth years) ÷ 200,000 (years it’s taken our civilization to be as advanced as we are now) @ 6,802,400,000 (estimated population)
= 23,000 (give or take a few) civilizations that could have reached our current level of advancement or higher (theoretically). I haven’t forgotten
the slot for the dinosaurs to have their little run of existence. There are plenty of slots within that equation for them to have had their run.
If you’ve ever seen the show Life After People
on the History Channel it doesn’t take
long for proof of a civilization’s accomplishments to be consumed by Earth through erosion. I can’t recall how far in the future the show actually
goes off-hand, but even when they go a mere 1000 years after people, there isn’t much left to show for our existence. Now add even 20,000 years to
that, there wouldn’t be much to go on as far as what the civilization had accomplished in their existence or how truly advanced said civilization
had actually become. With this notion, the remnants of civilizations of previous existences, that may or may not remain for us to see today, could
have stemmed from elaborate intelligent infrastructure from these past civilizations.
An example of these types of structures and remnants:
Ancient Underwater Road Discovered in Wisconsin
and the ever popular…
…albeit farfetched in my opinion, this…
Who Left Us an Alphabetic
Message Over Four Billion Years Old?
The aforementioned is just a theory I have and I am sure of the fact that I have not accounted for multiple variables. Merely suggesting that we think
we’re this uber advanced civilization, when in fact we may qualify as mere apes in comparison to civilizations that theoretically could have
inhabited this planet many times over, in the same respect, we could appear as Gods to other civilizations that may have inhabited Earth.
Look forward to your thoughts and opinions.
