The chances of an alien invasion are about zero. If an alien would come to earth, it would probably be one ship with a few scientists studying these strange creatures called humans. It would not be millions of creatures trying to take over the world.
What would the aliens want? Petrochemicals are available for free in places like Titan, water is all over the universe as ice. The idea that Earth foods (or people!) would be nonpoisonous or nontoxic is a big assumption. The odds of ANY Earth food (or people!) having even one of the vitamin-equivalents used by the alien's bodies is rather slim. On Star Trek you can just wave your magic box toward alien food and know it is OK. Don't count on this in real life. That leaves mineral wealth and slaves. Aside from coal, no mineral on Earth appears to be unique to Earth. If you have the tech to get here, the odds of you still using slaves or coal is somewhat thin.
There is no proof that aliens exist. I believe there is no such thing as aliens. Has anyone seen an alien ship? Has anyone seen an alien? No.
Nothing. There are no aliens known to exist.
If space aliens do indeed exist, they exist for the same reasons we exist. Whatver those reasons may be.
There is no evidence that aliens exist therefore the biology of aliens, if they do, is unknown
No
aliens, Might exist but their are rumours that they probe people.
its not that u are cray if u think aliens exist ,if someone says the exist and someone says they dont exist , just respect there answers
If we were there, we would be aliens. If they were here, they would be the aliens. Depends on the type of alien.
I don't think they eat anything. You have to exist to need food, and no aliens are as yet known to exist.
if aliens do exist, then yes
No, I do not have pictures of aliens as they are purely speculative beings that have not been proven to exist.
According to most people, aliens would ride in saucer-shaped UFO's. It is not known if aliens exist or not, so we cannot know for sure if aliens exist, let alone what they actually ride in.
