Modern humans have been around for 200,000 years.
this is a complete question?
No. They are a separate species - from another planet, the "Ood Planet" - who have been enslaved by humans.
Humans have walked the earth for the last 50 - 200K years. There have been earthquakes since the formation of the planet ~4.5 billions years ago - long before humans were around.
Apart from Earth, no humans have ever been on another Planet, whether they be Canadian, Irish or Bengali.
mars has been a planet for about 4.6 million years.
Mars is the red planet. No robots have been seen there. Humans have sent robots there, however, to measure water levels, scan for life, and take pictures.
The planet is worse off with humans.
as long as humans
Earth. Humans have not set foot on any other planet. We have been on the moon, but the moon is not a planet, it is a satellite of earth.
Earth is the ONLY planet suitable for humans.
Yes, apart from earth. (Technically the moon is not an actual planet, so technically the only planet humans have been on is Earth). There is talk of sending a manned mission to mars, though it seems unlikely.
not sure i think humans have legs know i have visted the humans planet 'earth' nice planet.
