Archaebacteria are the oldest and most primitive forms of life on planet Earth. It is postulated that primitive life on other planets would be most likely to resemble Archaebacteria.
In addition, Archaebacteria were the first life forms to exist on Earth, so studying them allows xenobiologists to postulate how life may come into being on other planets.
Studying the earth helps scientists to understand other planets since the earth is part of the solar system. Scientists use the features of the earth to compare them with what other planets hold.
All life as we currently know it cannot exist without water (H2O). Scientists look for signs of water when searching for life on other planets.
C. Since Earth is the only planet that we know of with life on it, it is obviously the one that we study when it comes to the subject.
so they can find out about the early solar system and how planets were formed
stuff you for searching this

mars because the scientists are searching right now
They live in conditions similar to those likely to be found on other planets.

scientists are studying about life on mars, but unfortunately it is still unknown! there is still no life on other planets.

So far yes, but scientists are still searching for other life forms on planets such as Mars.

They are gas planets
planatarium:)
stuff you for searching this
what molecule do scientists look for when they are investigsating the possibility of life on other planets
