Does Earth have life on it?

Earth is the only planet in the universe known to possess life. The planet boasts several million described species, living in habitats ranging from the bottom of the deepest ocean to a few miles up into the atmosphere. Researchers think far more species remain that have yet to be described to science.Nov 9, 2021

Without the Moon, there would have been no life on Earth. Four billion years ago, when life began, the Moon orbited much closer to us than it does now, causing massive tides to ebb and flow every few hours.

Will the Betelgeuse supernova destroy Earth? No. Whenever Betelgeuse does blow up, our planet Earth is too far away for this explosion to harm, much less destroy, life on Earth. Astrophysicists say we'd have to be within 50 light-years of a supernova for it to harm us.Feb 4, 2021

Betelgeuse Will Explode Someday

If Jupiter were about 80 times more massive than it is, nuclear fusion should have been possible, making it a small star. What might have been the most likely effect on the Earth? A) Jupiter's moons would have been likely to develop life, which would have competed with life on Earth.

No. Whenever Betelgeuse does blow up, our planet Earth is too far away for this explosion to harm, much less destroy, life on Earth. Astrophysicists say we'd have to be within 50 light-years of a supernova for it to harm us. Betelgeuse is nearly 10 times this distance.

Earth is the planet we live on. It is the only planet in the Solar System with liquid water on its surface. It is also the only planet we know to have life on it. Earth is also known as Terra.

Possibly, but probably not. It is not known when life formed on Earth, but Earth was once part of a nebula, and it now has life. Most likely life got started on Earth after the solar nebula was essentially gone, but that is not known with certainty.
