i do because if you look at this,this planet is called Kepler-20f it looks like earth people from NASA sent a satellite into space to orbit this planet and take photos and videos of its movement,they say it looks like it has water and land on it but not to sure....i think this is the next space launch

also the planet is orbiting around a star which is giving the planet heat which could mean life

Surely their has got to be , their are so many planets and galaxies.

If everything you can see is matter.
Then there is an opposite of it, like antimatter.
So in an anti-universe there must be a copy of you.
Not sure if you would count this as life, But it is very likely because there is an anti everything.
But even though we haven't found aliens yet, It has to be likely that more life can exist in our galaxy alone.

It doesn't look like water, Maybe it could be a methane atmosphere with liquid methane oceans?
