This seems to be the new thought of many scientists, and I keep hearing it more and more.
I get the idea that a planets environmental hostility makes it nearly impossible for life forms to survive long enough to evolve into technological beings, but the idea that it has only happened here seems crazy to me.
They acknowledge the universe is likely filled with habitable planets. It's as if they are using that likliehood as a way of concluding there must not be any life out there, in other words, since there are likely habitable planets throughout, why aren't we finding life ? Life must be a complete fluke.
The conclusion then is to say we must be the only ones.
"What happened here was a fluke - and is highly unlikely to have happened elsewhere", the researchers say.

The reason there has never been a confirmed sighting of an alien - or a message from an alien race - could be very depressing.
The reason we haven’t heard from aliens is because they’re all already dead, a new study has suggested.
Researchers from Australian National University suggest that the environments on early planets tend to be so hostile that even when life arises, it is quickly exterminated.
‘The Universe is probably filled with habitable planets, so many scientists think it should be teeming with aliens,’ said Aditya Chopra from the Australian National University.
‘Early life is fragile, so we believe it rarely evolves quickly enough to survive.’
‘Most early planetary environments are unstable. To produce a habitable planet, life forms need to regulate greenhouse gases such as water and carbon dioxide to keep surface temperatures stable.’’
