have aliens vist earth any time
Neither aliens nor time machines are known to exist. They sure do, they are called clocks.
Aliens, as in illegal aliens from Mexico or Guatamala? This morning. SPACE aliens who have come from another planet? Never.
ben has 1,000,900 aliens in his omnitrix
Aliens do not existfor the last time cheese
Yes, as a member of the Immigrant Support Soceity I talk to aliens all the time.
The Omnitrix (the watch-like device he uses to transform into an alien) has 10 aliens at time. But it happened that Ben managed to "unlock" more aliens by collecting their DNA.
There is no evidence that Earth has been invaded by space aliens.
As far as we currently know there are no aliens and therefore at this time they have no importance. However, should we discover that there are aliens then this will be VERY important and may change the world. It is therefore probably quite important to try and find out if there are any aliens.
build a time machine and see
from aliens in a long time or the sun will die.
