"1. There is no reasonably inhabitable planet in our solar system."
Build domes, build stations to accommodate industry and people.
"2. Traveling outside our solar system is unrealistic. (i.e. time, mass, etc.)"
Supersonic flight was unrealistic until it was not. Metamaterials and new forms of energy production may make such concepts as the Albercurrie drive a
"3. Anything which would destroy our planet would disrupt other planets in our solar system."
But they, just like we are still around and have been for billions(life) of years, time enough for whole species to rise and fall a few times.
"4. Humans are not entitled to eternal life."
That may be the case but any AI we may manage to create might be entitled to such.
"5. It's 'fun' to think about landing space craft(s) on planets like Mars, but humanity will never go there. Ever."
Why not, when we find something of value we generally tend to go get it.
"6. The more we think about 'escaping' our planet Earth, the more we ignore surviving on our planet Earth."
Cant have all our eggs in the one basket any longer, they are going bad as it is.
"7. Speed of Light travel is not possible by humans. Period. (Despite how cool it might be to think about)."
Which is why we need to somewhat circumvent/bend/fold space-time rather than travel faster than photons.
"8. Less than Speed of Light travel will never take mankind to another galaxy."
But it will allow us to colonize our own star system which is a noble enough endeavor and may lead to our understanding of how to transverse the vast
distances between star systems.
"9. ET doesn't exist, at least not in our existence on this planet. And, if he does, we wouldn't know him."
That's rather a fatalistic outlook, another way of looking at it is its only a matter of time until we discover life in other places aside from our
"10. The human form is not robust enough, it is far too needy, to explore he world outside our planet. The planet Earth."
We have made it to the bottom of the Marianas trench i think we are robust enough for space travel as long as we design out vessels to accommodate our
needs adequately so, inertia is the real issue.
