Hello.
I've read an article about the existence of a second life on our Planet in a science magazine. The article said that it is possible that it exists in form of bacteria and that it could be a reason for some diseases in our body. Can this be true?

A second life? As in: there is only one life on our planet? []

Could I ask, which science magazine this was?

Maybe he was refering to http://www.thenakedscientists.com/forum/index.php?topic=20943

At a push I think what he might mean is that:
Life is theorised, by many, to have began with some proteins and energy, such as from an electrical storm.  (Proteins, right?)

Now, it's also theorised by many that all life descends from an initial reaction of this nature and can be traced back to the first self replicating reaction.

So, could it be that bacteria didn't come from the same reaction as all other life, but from another one, in another gloop puddle somewhere else in the world?

LOL

But yes, there is a form of live which is not like ours on the planet. Namely, takes it existence not from the sun, but from the earth's crest heat. It resides at ocean depths near the crack where energy is released.
