the earth is a sphererical

Yes it is spherical: that's what the question says, sort of. We can inhabit it because firstly wherever you are on the planet, "up" and "down" are the same as anywhere else thanks to gravity hence those two directions acting radially from the Earth's centre; and secondly because it is so big the curvature is usually negligible within a radius of some miles from any given spot.
Hopefully that will never happen. Hopefully people will take steps to prevent that from happening. The earth has an amazing capability to cleanse itself, unless there is some terrible catastrophe, like a meteor smashing into earth humans should always be able to inhabit the earth as evolution causes ones to adapt to the environment.
Probably never. There is no atmosphere, and the temperature that close to the Sun will burn your skin in a flash.
The suffixes that turn "inhabit" into an adjective are "able" or "ant", resulting in "inhabitable" or "inhabitant".
I think they discovered that the earth was round. I don't know for sure :)
because if it was square we would be able to fall of the edge of the earth and we would have ran out of water ages ago!!
He has been killed and he died without being able to prove it.
from the earth's strong gravitational pull, when something is so large it has a gravitational pull other objects are able to orbit it
Even though the earth is round, or more specifically, spherical, it seems flat to the human eye. This is because the earth is so huge that when we look at it we can't take in all of the horizon because we are so close. If we were viewing the earth from the moon, we would clearly be able to see it is spherical.
whenever nasa or whoever ae able to send people to mars
I have no Idea man. Or Girl, whatever you are. JK!! He sailed across the world with his crew and didn't fall of the earth, he went forward and back. Sorry about the start.
The suffix that turns the verb 'inhabit' into a noun is 'ant'; inhabitant.
While some land is uninhabitable most isn't. With new technology people are finding ways to inhabit land they once may not have been able to. People live on steep mountains and deserts now.
