It depends on the concept of space and time.
Now there are many cases of which I'll explain 2.
case 1: Space and time are infinite and they have no beginning and end.
In this case aliens do exist. There is no question of them not existing. But they may be very far away. Too far away for us to ever know. It's math.
Case 2: Space and time have a beginning and are limited.
In this case they may or may not exist because the chances of conditions being suitable for living (like on earth) on other planets have decreased from infinite to limited.
Other than the "allegations" from the UFO trackers, we have no evidence to date that ANY kind of life exists other than on Earth. However, Earth lifeforms have traveled outside our solar system aboard our space probes (decontamination is only "nearly" perfect), and to the other solar planets due to meteor impacts in the past 100 million years (the same way Mars rocks were blasted into space and reached Earth). As far as whether life developed separately on some Earth-like planets (which should exist), it remains to be seen.
There is bacteria on Mars, but that's it at the moment.
If there are, we don't know about it. However, in a galaxy of 400 billion stars, it seems likely.
We dont know yet but maybe we will in the future.
no one knows for sure.. Considering the size of the universe, it would be bigoted to presume we are the only life out there.
if the planets werent real we wouldn't be hereUh I know Right if planets were not real we would not even be alive!
No planets are known to contain life, except for our very own Earth, at the moment. Although, there could possibly be life on one of Jupiter's moons, called Europa.
no, that's what most people believe.
lots of people have different opinions or theorys on wether this is true or not.
yes it is most likely
they want to see why other planets are differant from earth and want to learn and study other planets!
souljha boy bch
what do you mean use other planets?
no thunder does not appear in other planets
There are many other planets in many other galaxies.
NO- People have found water on other planets but there is no life there.
they want to see why other planets are differant from earth and want to learn and study other planets!
Yes. On other planets, we're the aliens, and we're real (unless you're into solipsism, in which case it's just youthat's real).On this planet, though... most scientists suspect there must be life somewhere other than Earth, but we haven't found any real evidence of it yet.
Because we can see the nearest planets through telescopes and for those much further away we can detect them by their effect on other planets and stars.
None that we know of.
No. because we have only 8 planets. But in a way if you were doing a project and it was about made up planets you could say they are real planets.
The inner planets are different from the other planets mainly because
there is more planets in our solar systems but scientist do not say they are real for example there is one farther then pluto called setna
People have only been to the moon. However, we can still see other planets using telescopes, satellites and probes.
yes some
Some people believe that spaceships from other planets have visited Earth, but no one has ever been able to prove it.
no their are not people living on other planets because where would they get the oxygen to breath or food and drink
