We do not know. We have not made contact with any aliens.
because they are just like human beings. we need oxygen.
We don't know !!!! But i think the "dead" does not need oxygen though
Yes aquatic life does need light and oxygen
Oxygen is the gas humans and animals need to breathe in.
Oxygen comes from trees you need oxygen to breath
There are no such things as aliens!! I dont know who told you that lie! thank u
Aliens need a home and a job.
To the extent that aliens exist, we can only assume that they do not necessarily respire--and if they do, they do not necessarily need oxygen for their particular metabolisms. Hello,Friends my name is Micah Wilson George.I am aboy of 11.I want you to answer my question please. "Living things survive because of oxygen.Alien is a living being,but how can they survive without oxygen?"
probably around the same things we would need to survive oxygen or water food or some other source of energy gains as constantly as needed
Aliens probably could live on earth. As far as we know there is no life that can survive with out water food and oxygen.
No. What makes you think that aliens need doors?
no, you'll need spardex aliens try putting to aliens together on there backs coverd in the slime they provide you
if there is water if it is at the right temperature how long it would take us to get their how much fuel we would need in a rocket to get to mars are their any aliens or harmful animal their is their enough oxygen etc.
The aliens need to use earth's satellites so that they can coordinate their invasion efforts.
because they need to drive to mcdonalds
because of aliens
I don't think they eat anything. You have to exist to need food, and no aliens are as yet known to exist.
