explain?

i believe in other life forms for sure, why not, like if we can exist, other life forms on other planets can also exist i think, with their own habitats and ecosystems

People hugely underestimate the vastness of the universe... And there's also a very real possibility that the universe is yet another speck in an infinite expanse of universes. Its on a scale that the human mind just isn't cut out to really comprehend.

Basically; not only is it likely that there is other life, but the sheer vastness makes it highly UNlikely that there aren't aliens somewhere out there that are approximately the same as humans. Possibly not in this galaxy, but there are unimaginable numbers of galaxies.

That said; faster than light travel may well be physically impossible, and if that's the case, then travelling between galaxies would be basically impossible also, no matter how advanced any alien race becomes.

So the universe might be absolutely full of life... With most of it never actually making contact with another intelligent species.

Of course, again, the vastness means that it's statistically likely that somewhere out there, there's a solar system with two or more planets hosting intelligent life. Some species get all the fun :hmph:

Again though talking about the galaxy totally underestimates the vastness of the universe. Even if we were the only intelligent life in the galaxy, and even if life came to be on earth by infanitesimally small chance, that still underestimates the scope of existence. Our galaxy is a speck of dust on an unimaginably massive canvas, and even the tiniest freak circumstance stretched out to a scale of (potentially) near-infinity becomes commonplace.

I hope if there are aliens they are more like the Xenomorphs from the Alien films rather than super intelligent beings

I agree with both your posts T.S. - especially that man's brain is not capable of REALLY comprehending the sheer vastness of even the KNOWN universe.

I read that there are more 'galaxies' than there are grains of sand on EVERY beach and in EVERY quarry in the world.

Similarly, our brains are incapable at this present time of fully grasping the concept of Faster Than Light space travel, but SOME alien species have had interstellar flight for thousand of our years because they have left their 'footprints' all over our world throughout thousands of years.
