Earth may be a nice and cozy place for life as we know it to evolve, but is it really the best place for life to thrive? Probably not, say two researchers. In fact, Earth may be one of the more extreme examples of a “habitable” world where life was lucky to survive.
The search for extraterrestrial life is fraught with uncertainly. Faced with a seemingly infinite Universe and an assumption that life beyond our planet is an inevitability, we focus on nooks and crannies that have similar habitable environments to Earth and exoplanets that resemble our world orbiting stars that resemble our sun. But finding these special places feels like we’re looking for a very specific needle in a very big haystack. What if our definition of “habitable” is just not all that, well, habitable?
“The Earth just scrapes the inner edge of the solar system’s habitable zone — the area in which temperatures allow Earth-like planets to have liquid surface water,” said René Heller of McMaster University, Ontario, Canada. “So from this perspective, Earth is only marginally habitable. That led us to ask: could there be more hospitable environments for life on terrestrial planets?”
Looking at the history of our planet, it may seem amazing that life was ever able to gain a foothold. Between the asteroid and comet bombardments, intense volcanic activity, frigid ice ages and often poisonous atmospheres, how were the conditions ever ripe for single celled lifeforms to form? Perhaps life was just really lucky to have found its way in such an inhospitable place....

Yup. Check out Congress and the White House. You’ll find aliens there....not necessarily intelligent, though.
I was just going to say — we keep on asking ourselves about aliens, but who knows that they are perhaps already here but unrecognizable from the rest of us.
Is this ‘Speculation News’ ?
Check California, New Mexico, Nevada, Arizona, Texas, Florida, well heck, just about anywhere..
Hint: Most aliens speak Spanish...
” life was ever able to gain a foothold”
What does this mean? How did the RNA and the DNA “get a foothold” without cells to encase them?
The cells alone have 300 proteins. A single strand of DNA for simple life forms has more information that all the books in the library of Congress.
Yep, kookie there — Life got a foothold. Isn’t it wonderful. HOW?
Here’s where to look:
Check the parking lot of the nearest Home Depot.
‘I find your lack of faith disturbing’
Yes. Alpha Centuri B. His birth certificate’s probably up there.
So says a fictional character, Darth Vader. But every time I try to debate the facts with you, you go into super-irrationality mode. So, go ahead and quote fictional sources to bolster your fictional point of view.
Step two is also causing Man Made Globull Warming.
You can find a whole bunch of aliens at Home Depot every day.
I’ve heard that the best place to search for aliens is the parking lot at Home Depot or Lowes.
