Earth was created 8 billions (roughly; a million or two is unsignificant there, and more unsignificant even to meet my point here) of years after the
Big Bang. That is, by then, some things out there for about double the time that our earth exists.
Life exists on earth for 600 millions of years. That is actually Big Bang + 13 billions (yes, I said that a few millions were insignificant, and I'll
stick to that). That is 20 times the time life exists on earth (roughly).
What now, will you tell me... Well, planet formation is now know to be far more common than previously believed and also far more ancient. A few
months ago, a planet 13 billions (yes, billions
)) of years old was found around a star that was still in its main sequence. 13 billions
is actually between 8 and 9 billions of years older that us. That being said, planet formation has happened as soon as there were stars, and that is
precisely just after the big bang...
Given the immense number of galaxies (infinite maybe), the amazing number of stars in each of those galaxies, and the fact that planet formation is
now believed to be far more than a scarcely happening event, we are left with a likely several millions (billions maybe?) of planets being way older
than ours (I'm talking about here about dozens of millions of years older), and a likely (my view) several thousands of them harboring evolved life.
Evolved for far more than here...
Honestly, I would be extremely surprised if we were the most advanced... Would it only be the oldest and I'm fainting... In my views, we are likely
(in "their views", then) largely primitive, extremely unevolved, on the eve of an early form of civilization, or things like that...
On the other hand, we ourselves in that particular position could well be finding (here or in other systems) some life forms that we would just
qualify with the same words...
No links for now... Too lazy. Anyone requesting back up info is likely to see something but not now...
Anyone interested anyway can find links
about the things I say. I don't think I went wrong anywhere with this. If so anyway, apologies!
