Since they say the Universe is ever expanding, then there must be room out there or it's making room. Some how some way.
Life? Hmmm, Odds are there IS some form of life in many other solar systems. Whether it is something we cam recognize is something open for conjecture.
Could they travel here? Having grown up when the original Star Trek series came out,... everyone scoffed at all the neat things they portrayed on that show. But wow, they have made most all of that come true just in these few short years, So odds are, IF there are folks out there, they could hide from us so easily it's not even open for discussion.
If we travel out there with some sort of propulsion to cut down the distance - time thing, they would have SOME sort of (trekkie) tricorder that would hopefully recognize lifeforms or be able to adapt to it.
And as they say, Kree Gloc kahh! Who knows. lol None of us will be alive to experience it. Maybe when Dick Clark finally decides to pass, he will enlighten us what they have found after we have passed. We all know he has about 500 more years of life left in him.
