There are dissenters, but the Big Bang model is very well established at this point.Is this true, I though that it is still an open question. we do know it is bigger than we can observe.
True. Do you know how many amino acids exist in nature? About 500. And of that 500, only 22 of them appear in the genetic code of all life on this world alone. Amino acid - Wikipedia While they might not be life, they are the building blocks for carbon-based life, as we know it.So, amino acids are not "life". Amino acids don't even replicate themselves. There are no amino acids used in terrestrial life that can be shown, or even be reasonably argued, cannot easily arise naturally given a complex chemical soup and some energy (like radiation, volcanism and lightning can provide).
Thus, "amino acids are seen on meteors" doesn't make a statement about the origin of life. It makes a statement on the ubiquity of conditions to create amino acids - and thus that amino-acid-based life could also be ubiquitous.
In an infinite universe containing infinite matter, everything that appears once can be expected to appear an infinite number of times.Statistically speaking, in a infinite universe, other intelligent life is pretty much assured.

The big bang does not make the universe finite. Even if it is finite there is (as far as I know) there is no consensus as to how big it might be. It is bigger than what we can see or ever see.There are dissenters, but the Big Bang model is very well established at this point.
That kind of depends on what you consider the Universe to be. The portion of the Universe from which we can currently receive signals has a finite size, since our Universe began 13.8 billion years ago. If the current phase of accelerated expansion will keep going on forever, we will ever be able to observe (or send signals to) a portion of the Universe that is 2-3 times larger than what we currently observe, even with infinite time. From this point of view, the Observable Universe is indeed finite.That's...not accurate. The universe is big, but finite.
There is no current scientific consensus on whether the universe is infinite or finite, we simply do not know with any certainty.In an infinite universe containing infinite matter, everything that appears once can be expected to appear an infinite number of times.
But we do not live in such a universe.
That is precisely what it entails: finite in size, and with a finite starting point. As evidence points towards the heat death of the universe being the end, it is finite in time ilin the future, too.The big bang does not make the universe finite. Even if it is finite there is (as far as I know) there is no consensus as to how big it might be. It is bigger than what we can see or ever see.
