Answer:

Hey Mate

Everything we know about life comes from a sample size of one: life here on Earth. And the fact is, we don’t really know exactly how life arose from inorganic matter all those billions of years ago … and who’s to say that different processes might not have taken place on different planets out there in the universe? Perhaps there are more questions to ask, more possibilities to consider. But let’s start with what we know about some of the very first living things on Earth.

Cyanobacteria, also known as blue-green algae, started out on Earth quite a while ago. Possible fossil examples have been found in rocks that are around 3500 million years old, in Western Australia.

Although commonly referred to as blue-green algae, cyanobacteria are not actually algae. Cyanobacteria, and bacteria in general, are prokaryotic life forms. This basically means that their cells don’t have organelles (tiny structures inside cells that carry out specific functions) and do not have distinct nuclei—their genetic material mixes in with the rest of the cell. This characteristic is distinctive of bacteria and archaea; all other life forms on Earth, including real algae, consist of eukaryotic cells with organelles and with genetic material contained in one place (the nucleus).
