Since Earth is in space and we are inside the Earth, doesn’t that mean we’re inside a globe?

Do aliens come on Earth or Mars and we sometimes see them and sometimes not?

No alien that we know of has ever come to Earth.

As far as not seeing aliens, some aliens are microbes. Probably most are microbes. It’s hard to see microbes without a microscope.

How will space be used for military purposes in the future?

It already is being used for military purposes right now as in spy satellites. Even very recently SpaceX was tasked to launch a U.S. spy satellite into orbit but it exploded and the satellite didn’t make it.

In 1984 a Titan 34D rocket launched the KH-9 and KH-11 satellites for “reconnaissance,” and the DSP-2-6R satellite for missile detection. The list just starts there and goes into the hundreds including many intelligence-gatheringsatellites and so on.

And, by the way, not just by the United States, but other governments as well.

Furthermore, the Chinese government once shot a missile to destroy their own satellite in space just to say the could, and they succeeded, vastly increasing the dangerous debris cloud floating now in orbit. It was a military demonstration.

Why is there a stigma around attempting to discover extraterrestrial life?

There is no stigma. All of science is dedicated to discover extraterrestrial life. We would be completely excited to find even a fossil of a microbe from space because it would be the ultimate affirmation that life can evolve from matter on another world other than Earth. Our best hope at present is to find some kind of life on one of the moons of Jupiter or Saturn, or perhaps some fossils on Mars as of yet undiscovered. We are even spending billions of dollars with the SETI program to listen for radio waves from space!

However, much to the surprise and dismay of scientists, we have yet to discover anything at all.

Perhaps human race’s home was not Earth in the first place, but in another planet, and we came here to prevent extinction

Mechanical, intentional interstellar travel is unlikely since the distances are far too great to imagine. The best anyone could achieve is interplanetary travel within one’s own solar system. Therefore, if we pass the buck and say life didn’t start here but started somewhere else and arrived here, it would have had to arrive on a rock or asteroid as a microbe and somehow survive a fiery entry through Earth’s atmosphere and it would have had to survive the vacuum and temperature extremes of space. If the rock came from outside the solar system it would have had to survive a long, long time.

When is the next time a human will walk on the moon?

After awhile, walking on the moon got old. It cost a whole lot of money and there wasn’t much to do there. The Vietnam war was sucking the budget. We were sending men up there to kick around the dust and rocks, drive rovers around, and it – as I said – cost a lot. Can you give me a good reason to go back?

Andy Weir’s “The Martian” provides a template for what a realistic mission to Mars could be like, yet most science news I hear about actual proposed missions appear to be just a big Apollo. Don’t we have to do it in Weir’s way to succeed?

No. Andy Weir’s “The Martian” was science fiction. It was a possibility, but not a reality at present. Don’t confuse science fiction with reality.

We shouldn’t go to Mars (in my opinion) but we are going anyway. That being said, we have to wait and see how it plays out in reality, not in sci-fi.
