Not yet.
SETI
no, exept for us humans.
It has not been clear that there is alien life.
No. To date there is no proven direct evidence of extraterrestrial life.
Technically, humans are not a type of alien, since the word 'alien' pertains to 'foreign', and humans are not foreign. However, if there is another intelligent species that is out in space, humans would be alien to them. It all depends on your perspective.
Unfortunately, no extraterrestrial life has been discovered to date, but astronomers are always on a close lookout!
Alien life on other planets has not yet been discovered. Furthermore, the distance of Venus from the sun makes it an unlikely candidate for alien life, since it is far too hot to support life as we know it. Therefore, it is not possible to meet an alien at this time.
For Humans, the same as in real life. For aliens depends on what species the alien is.
Humans are alien to other Planets. The only place in the universe where humans are not alien is here on earth. However we can be alien to another nation in regards to race and culture.
All planets other than Earth could be considered alien. Earth is the only planet known to harbor life.
yes i think so but if alien s exist then they can also be intelligent
From the data we have, we have not discovered any alien races.
