Amino acids were found in the Ryugu asteroid in 2020. If this result is reproducible in other labs, I think the water hypothesis seems believable...

If Panspermia is true, then can we consider life on earth as alien life?

Might have?

How about definite proof?

Yeah, but God threw the asteroids here.

A little bit of water brought from an asteroid here and there cannot create even more water ( like enough to cover over 70% of the earth). It can only rain as much water that was evaporated from x amount of water in the first place. Then the whole water cycle begins again using the same amount of water. We are still drinking the EXACT SAME water that has been here from the beginning of time. The world is a master recycler.

Its shocking how messed up science can be.

Asteroids may have brought water, organic matter to Earth:

'May have'. Why are Japanese researchers saying that now? Something is amiss.

That has been a long foregone conclusion made by other scientists years ago..

Or maybe water is created deep within the earth (look up Primary Water) through pressure. A couple of examples are Gaddafi’s ‘great man-made river’ water supply project (before it was bombed) and springs which tap into this source as it makes its way to the surface.

New Evidence for Oceans of Water Deep in the Earth

Researchers from Northwestern University and the University of New Mexico report evidence for potentially oceans worth of water deep beneath the United States. Though not in the familiar liquid form — the ingredients for water are bound up in rock deep in the Earth's mantle — the discovery may represent the planet's largest water reservoir.

They need hypothesis for more funding. The longer the hypothesis thrives, the longer the funding is. Just look at cancer and AIDS research, and now, Covid.

I don't understand if this is criticism or not? Testing hypotheses is the basis of science.

Microbial flatulence and condensation.

Billions of years of it and look where it's gotten us .

The hypothesis of asteroids bringing life to earth isn't new news.

Fascinating topic .

The world is a master recycler

It can only rain as much water that was evaporated

Everything is expanding ,dividing and growing .

Not just being recycled.

Not all water that is evaporated forms clouds that rain because it also creates wind.

It's a cycle which creates momentum /electricity/ energy

Everything is moving.

There must have been an awful lot of comets then to bring that much water.

Follow the science. (money trails, funding, etc ) That's how 'science' works these days.

I believe this has been a strong theory for quite some time now. Why they are announcing as some kind of novelty is odd - except, as others have said, for funding purposes.

And we brought climate change/global warming, air, water and sea pollution.

More evidence is being found but this thisn't really new, or a new idea either.
