Question: Where does bacteria come from?

Christina Pagel answered on 21 Jun 2013:

Bacteria are living things – they are tiny little living things called microorganisms – so small that we can’t see them with the naked eye…

They’re everywhere- on all surfaces, on our skin, in our guts… in fact mnay bacteria are good for people (without them we couldn’t digest our food) but of course some bacteria make us ill…

Bacteria were also one of the earliest life forms to evolve on earth and you could say that there were the most successful since billions of years later and they’re still here and thriving!
