while watchign a documentary about how water and other compounds for life as we know it, are found throughout the solar system I have begun puzzling at history. Early universe history that is.

The organic compounds that were delivered to (probably all the planets of our solarsystem) earth by comets had to have come from somewhere.

Maybe, bacteria and what makes them, are very hard to kill. They can lie dormat in frozen cores of comets for aeons and then thaw when the thing crashes.
The supposed discovery of alien bugs in the upper atmosphere seems to support that theory.
It is confirmed, however, that at least components of nucleic acid are present in comets.

Our sun is a third generation star, meaning that after the big bang a star formed. Much bigger, much brighter and much hotter than ours. It burned out quite fast (in stellar terms), blew up and left material behind that hasn’t been there before.

During the normal fusion process of a sun burning there is Helium created by fusion of Hydrogen. But in a supernova all the other stuff is created! Everything that we know, and are!
It is all created in a violent explosion.

The second generation star might already have had a planet with life on it, or at least a primordial soup sloshing around in it. Once that one blew up these building blocks of life might have remained withing the zone of destruction, our sun formed in that cloud, so did our planets, and earth. The entire system might have brought life to itself. Or it happened like this and life came from somewhere else entirely. (Go back to Panspermia)

Perhaps life is just like the religous people claim for their gods: Omnipresent.
It has a chance to sprout everywhere in the universe, and does so quite often. Only recently remnants of a solarsystem had been discovered in which a planet once had existed that consisted of 20% water! (Earth consists only of 0.02% water, the rest is rock. Please, don’t confuse the entirity of the planet with just the surface.)
Just think about that. A planet that is 20% water! How much life could be there?!
A friggin lot.
Perhaps there were water aliens. Maybe they built spaceships and left their planet before the star died taking their homeworld with it. Someday they might turn up on our little planet, a rather dry spot for them, but it might suffice.
Perchance they drill down into Europa’s surface or Enceladus’s and make a base there?
What we might find out there in the universe is beyond count. Beyond imagination. We will find life, sooner or later (if we don’t kill ourselves before then, that is)

What ever the truth is, it is beyond us for the moment, but we will find out sooner or later. Perhaps there is life based on other substances than carbon? Who knows. Let’s land on Titan, and find out. I figure it is the best spot to look for alien life based on other elements than carbon.

I hope we discover some sort of alien life within my lifetime.
