Blowing Scientists Minds

[Blondie]

Not sure if this fits here or what to call it exactly.  If this is under the wrong forum or misleading, I apologize ahead of time.

Hypothetically speaking, if the earth is as old as scientists state that it is, what would be the possibility of life existing on earth before what we know as life on earth today?  Would this be a possibility?  Has the scientific community considered this?  Could the possibility of proof exist scientifically?  Why or why not?  Besides the evolution theory, could this in any way explain the different fossils such as the different shapes of skulls that serve to most scientists as proof of the evolution theory? If this questioning of mine could be proven, how would it change the outlook of science as we know it today?

If the universe was nothing to start with and the Big Bang happened, then anything like this could be possible unless I am wrong on my thinking. I did try to google this before I asked and not much has showed up.

Funny you should mention it.  From yesterday.

Zircon crystal found in Australia suggests life appeared on Earth 4.1 billion years ago: researchers

Hypothetically anything is possible.  Science looks at evidence which is what you would need to produce.

Interesting you should mention this when the estimated age of life's origin just got kicked back 300 million or so years...

To the OP. in a word, panspermia. The boundary conditions that keep being pushed back are likely to conclude such - that's my guess, anyway. 

Although, if your looking for a way to depreciate evolution, this ain't it.

I'm not sure why you would think your scenario would be as revolutionary as you make it sound, but I think it's safe to say you don't understand evolution or the fossil evidence.

I'm not sure what you mean by this question.

Are you asking if it is possible that life existed on earth, in different forms, than it does today?

As in, no humans?

Only dinosaurs?

Can you clarify what exactly you mean by "life existing on earth before what we know as life on earth, today", please?

Simple life could exist during the early days of Earth, but that would be even simpler than the single celled organisms we have today, and thus you shouldn't expect to find any "oddly shaped skulls" from that period. If we do find that, we should start preparing for an alien invasion, cause that'd guarantee we are not alone in the universe.

I wonder what ever happened to that science porn thread

I didn't understand the query, and I suspect the poster is pretty fuzzy on whatever it was too.
