Perhaps as bacteria have been around millions of years longer than humans.
Bacteria have been around millions and billions of years longer than human on earth.
i dont think that this answer is right
There a pro's and Con's to this. Yes to the point that they are single celled organisms so they can easily sit around in a warm, damp and nutritious place (Known as your food recycling bin) and reproduce without a care of anything else. [Parasites are awesome as well as they just live off a host and no nothing... they get their warmth, dampness and food from just living inside of you. But don't keep them as a pet otherwise there is a chance of death] No, as they can't survive if you take one of those things away. And I don't see them creating Bio-domes in the middle of deserts or space stations orbiting the Earth. It depends on how you look at it and under what category you set it. Eg) Can you send them into space on a rock: Yes to Bacteria and No to Humans. Can they adapt to different climates: No to Bacteria and Yes to Humans.
As of now, the smallest bacteria on Earth are those belonging to Mycoplasma.
Bacteria live in and on animals, humans and plants.

dnosaurs, strange reptiles, fish, and bacteria. very vague, sorry
Bacteria CAN live on Earth.

Because they're better adapted to planet Earth than we are.
Yes, human beings were present on Earth during the Cenozoic era.
It is difficult to estimate the exact number of living beings on Earth, but it is estimated that there are around 8.7 million different species, including plants, animals, fungi, and microorganisms. The total number of individual living beings is in the trillions.
As of now, the smallest bacteria on Earth are those belonging to Mycoplasma.
the amount of bacteria on Earth would have to be at least over 100.
Every single organism on this earth has adapted to its environment... that is the beauty of adaptation.
Aliens, as people know, are living beings outside of the Earth. Scientists have not even discovered bacteria outside of the Earth ( as far as I know). So I don't think aliens can breath underwater, maybe in science fiction movies, but not in real life.
very well infact
