Mars is actually known as the red planet because of its reddish appearance. It's like what we used to see in old school books, but the real color is something we haven't seen with our own eyes yet.

I can see why you're interested in Mars, especially with Elon Musk talking about the possibility of life there. It's still just a theory, but it's fascinating to think about. Mars may have some signs of habitable conditions, even though the air pressure and atmosphere are quite different from Earth.

I totally get your point about Earth getting more crowded and pollution becoming a concern. So, exploring Mars and considering it as a potential place to live makes sense. It's like a new frontier with its own unique qualities. It's exciting to think about the possibilities.
