Why? You do realize that we are not extrapolating from our minuscule little corner, right? The red shift tells us that everything is moving away from us. That coupled with the solutions of Einstein's Theory of General relativity - which has been confirmed in a myriad of ways - tells us that all the matter in the universe occupied the space a million billion billion times smaller than a single atom and then expanded and cooled.I have no illusions that we will ever meet an alien speciesYou two might as well forget about the feasibility of interstellar or intergalactic travel. Any object with mass will have its mass approach infinity as it nears the speed of light, thus requiring infinite energy to continue accelerating towards the speed of light.
Maybe but then again maybe an advanced alien species knows something we don't
This is your opinion based on vastness of space. This is what atheist scientist Carl Sagan believed. He would not accept UFO sightings as he thought they were unreliable. It means there wasn't a sighting that a scientist would accept unless he was a weirdo. First, show us there's an advanced alien species. Can you show a single-cell one? Oh yeah, Carl Sagan sent time capsules into space for intelligent aliens to find, but still no response. He died with no evidence of aliens. I would think so would you.
If you'll noticed I qualified the statement you are responding to with "assuming they exist"
I do not doubt that somewhere in the universe another life form exists whether we will ever know that before we go extinct is another matter altogether
My bad. I was more open minded about aliens and another life form existing until I heard the fine tuning theory. Now I tend to doubt it. If there is, then there would be a good chance it escaped from our planet. For example, if we found bacteria growing on the moon. Moon Microbe Mystery Finally Solved
I think extrapolating the properties of the entire universe from our most minuscule little corner of it to be an error.
