I like this question so much i made an account here at ATS just to post.
-Earth is 4.54 billion years old
-The oldest known hominid, or humanlike species, has been dated at 4.4 million years old. Another species, which is yet to be confirmed as a hominid,
has been dated at 6 million years old. Scientists estimate that the hominid lineage diverged from the ape lineage 5 to 8 million years ago. Homo
sapiens, the species to which we belong, has existed for about 100,000 years.
Now the fun begins:
using these numbers, and a little bit of 'guessing' it takes about we will say 10 million years for a 'human like species' to evolve into what we
know today as human people.
if the earth is 4.54 billion years old
WAIT if theres no oxygen, or water on earth then we cant survive so i will google this 1st...
water- The Earth is about four and a half billion years old. It's difficult to study what the Earth was like back then, because the Earth's crust is
constantly being recycled, and very few rocks are that old. However, we do have a little bit of rock that is 4,400,000,000 years old, found on the
continent of Australia. This rock shows evidence that the surface of the Earth was solid and cool when this rock solidified, just 600,000,000 years
after the Earth was formed!
There was even liquid water present where this rock solidified!
So as far back as we have geological evidence of what the Earth was like, there was liquid water present.
ok back to my post:
4.54 billion - 600 000 000 = three billion nine hundred forty million
if evolution takes approx. 10 million years then IT IS POSSIBLE that apes (or insert your own method of evolution here) evolved into what we know as
humans 394 TIMES.
now still just guessing, and thinking,
but that means its possible, that evolution took place, build up to 'human' advanced, spread, thrived, and died out 394 times.
MY OPINIONS ON THIS-
this would in my eyes explain aliens - (maybe civilizations that existed millions of years ago, that advanced to the point of space travel, maybe even
travel faster then light etc. i mean they do have..well a couple billion years on us) maybe the planet was going to be destroyed by any means
asteroid, worldwide event etc. and they had to leave. and if an advanced civilization, or even OURS if we had the means would travel to the nearest
terrestial planet or moon.
This would also explain life and/or monuments (as speculated on the moon, and mars) or even jupiters moon Europa which in fact DOES HAVE WATER.
this would explain languages that are unknown but science finds currently on earth, maybe old languages from past civilizations.
this would explain the 'life cycle of earth recycling everything and starting over hypothesis" ive read that everything goes through cycles, and earth
is included in this.
just my 2 cents
