Panspermia revisited

Are we all "aliens"? Did all life on Earth originate elsewhere, with one-celled extremophile bacteria (and perhaps more complex, multi-celled organisms) spreading through space? Or is the situation even stranger and more complex than that, with organisms from other worlds arriving here, and bacteria and other life forms from Earth spreading out to "seed" other planets, moons, and comets?

Panspermia is hypothesis. When someone find one evidence that we can change it theory then it would be different story. 

There is no evidence panspermia hapoening or ever happened.

Errr...in science when there are no evidences its called hypothesis. When we have evidences its called theory. And there are scientific facts such as that we are circling around the sun. Common knowledge which everyone accepted. Ofcourse later have plenty of evidence. Science is self correcting. When we have new evidences or new theory about existing theory and so on.

Where would you put Panspermia? 

We have nothing to confirm it. Its fable, hypothesis, wild guess. I dont trust it a tiny bit.

All panspermia does is move the goalposts

Life had to start somewhere.

We have complex sugars and hydrocarbons, including alcohol in open space and extremophiles here on earth which could survive open space.
