“Seems like quite a few Class M planets.”
Humans have spent millions of years living in this biosphere; where we share similarities with every fungus, bacteria and virus. Every 150 pound human is carrying 5 pounds of bacteria, fungus and viruses. Actually, that 150 pound human has more non-human cells than human cells because that 5 pounds of cells are so much smaller than human cells. Our highly evolved immune systems keep the alien growths in check and balanced.
Now, imagine we go to another world that has evolved totally different analogs of bacteria, fungus and viruses. Those aliens will be right at home in our wet, nutrient filled bodies. Our immune systems won’t recognize them and we’d shortly be sprouting growths like forest fungi inside our eyelids. We wouldn’t make it a month on this new world.
Mankind will NEVER walk freely and unprotected on a life containing alien world. Science fiction whips up wonderful worlds and aliens. But if we ever meet them for real, no matter how “nice” they are; their bacteria will kill us; and vice versa.
YAWN!!!!!! The human race can adapt to any environment..

You're making major assumptions. First of all, you might ponder what "terraformer alert" refers to in the title of this post.
Secondly, you should consider that some fluke of our biology might be poisonous to every organism on said planet. Problem solved in that case.
Third, the biology there might not be based on DNA or any significant portion of our makeup (silicon based life?). Then we'd be of no particular interest.
A exoplanet "Garden of Eden" would most likely be massively terraformed and then an ecology of Earth organisms would be introduced, I'll grant you that much.

I agree that is probable, but it’s not definite. You can just as easily hypothesize the organic contaminants will be too alien to affect terrestrial body chemistry. That there would be no compatibility with any biology brewed up hundreds of light years away.
>>> Habitable planets orbit 1/3 of Sun-like stars
Very misleading and sensationalized headline. I don’t think they’ve found even one habitable world. They merely have found rocky planets larger then Earth in the relatively temperate zone where water “might” exist. It also doesn’t take account of the difference of conditions between the galaxy core where most of the stars are, and the spiral arms where we are.

This is why aliens probe humans up the poop chute, not because they are kinky, but to collect the bacteria that live in our guts to study them so they can adapt themselves to our bacterial flora and fauna.
