By searching in normal human.
I doubt that anyone knows. It would be hard to determine when that would be also.
If there ARE aliens then yes.... illegal aliens can have their own language No one really knows if there are aliens so you can't exactly say they have their own language, but we can infer that they might have if they are indeed real. Grenthels tordoly nif zehr ereln wenderlay. thats not funny!!!
Aliens, (in my opinion) are definitely REAL. Because several pictures, sightings, and encounters had happened. In fact the United States government even knows about it, they even try to hide it. People have found real aliens before the government just tries to hide it.
depending on the source the count ranges from 7 million to 20 million. No one knows for sure. Said to increase 500,000 illegal immigrants each year
No!who knows......maybe there might be aliens.
no one realy knows if aliens sexed
No one knows. We don't know if aliens even exist at all.
No-one knows for sure. Even no-one knows if there are even aliens! The people that think that they exist often say ; "The tecnology is beyond our imagination, no-one knows what it is."
Nobody knows yet
They aren't. There is no evidence for the existence of aliens and certainly no ground bases. Because they don't want people to know what they do with the aliens and where they are because then we would go try and see the aliens and ruin their experiments with the aliens.
No one knows for sure since it was impossible to count because it was illegal but the WHO knows today that in countries where it is illegal the amount of abortions is the same as if it was legal. It's just unsafer and more dangerous. Today there are 1,2 million legal abortions a year in the US.
Nobody knows the answer to this question because nobody knows if aliens actually exist.
