Only the imaginary kind have come so far.
There is no solid proof aliens even exist much less have visited Earth.
No, there are no aliens coming to the Earth or anybody's home.
probably
NO
No evidence says so.
Thats probiably because aliens dont like earth very much. Legend has it, That there is a 00.1% chance (small chances) for the aliens to come to earth with there UFOs. (i have seen over 4 UFOs in the sky before)
They come to make sure that you're eating your vegetables.
probably not in the earth, but VERY most likely far away. we will probably die off before we come into contact with aliens.
They are government agents who deal with aliens that come to earth
No aliens are actually known and proven to have ever done so, so asking "how" is a bit premature.
Extraterrestrial are unknown humans. They are humans, but different kinds from different planets. Like aliens and UFOs. The scientific community think this is true. They think they come from planets beyond Earth...
No they will not, the bible makes no mention of aliens, so there are no aliens.
