If there were no other bacteria, you would be right.
I think it is quite save to say that there isn't any fertile spot on Earth
were there aren't bacteria already. These bacteria likely have
overtaken/driven away all weaker kinds of bacteria and thus are the fittest
and most numerous for that particular spot.
The likelyhood of survival of a few bacteria that are not (yet) adapted to
that spot is therefore small. Assuming the spot is suitable for the new
bacteria, they'd need to be much stronger to get the overhand while being
attacked by a majority that has the advantage of being adapted best to the

Survival is something very different from thriving. I doubt that there are
bacteria that can thrive in a large range of temperatures. Anyhow, any
divergence from the optimum temperature for the hositle bacteria will give
the human body an advantage.
Our body can sense a very large scale of alien (not necessarily
extraterrestrial) substances. As far as I know it is not so that our body
has to learn what is alien, it merely checks if it isn't familiar to the
body itself. As soon as a substance is strange, the body will try to attack
it right away. I suppose the body has standard procedures for substances
that it doesn't have encountered before.

No, some creatures just can quickly enough find spots where our body's
immune system is very ineffective or hardly notices it. Other substances
like poisons are just attacking too fast for our body the react against (if
they are in large enough quantities). In general relative small quantities
won't make much of a chance.
