Many scientific theories are fact and will not change.
For example, all species on earth descend from a common ancestor. That's a fact.
Also, you need to understand a distinction.
We don't know exactly how abiogenesis occured. But that it did occur is a FACT.
I didst claim evolution did not happen and you can no more prove how life started then any one can prove god exists or not. A true open minded person who likes science who keep the possibility open because the FACT is YOU DO NOT KNOW FOR SURE.
Now I hate to do this to you but read this .
Abiogenesis is the idea of life originating from non-living material (non-life). This concept has expanded a great deal as mankind’s understanding of science has grown, but all forms of abiogenesis have one thing in common: they are all scientifically unsupportable. There have been no experiments demonstrating abiogenesis in action. It has never been observed in a natural or artificial environment. Conditions believed to have existed on earth are either incapable of producing the building blocks needed, or self-contradictory. No evidence has been found suggesting where or when such life might have generated. In fact, everything we know of science today seems to indicate that abiogenesis could not have happened under any naturally possible conditions.
Abiogenesis, as a field of scientific inquiry, is still in its infancy. It is not very far down the road of an accepted theory. The other leading theory is that life formed at hydrothermal vents in the deep sea. The heat and chemicals that would have been available there include naturally forming molecules that are "heavily featured in biology.
Its not FACT as you claim because it has not been proven , just as gods existence has not been proven or did proven. I am familiar with the 1952 experiment and no life was created and attempts to do so have all failed .
So as you can see its NOT FACT .I can say I think life came from space on a comet or asteroid its just as sound a claim as yours but can I prove it to be FACT .
Same with god I neither or you or any one can not prove he is real or not, No one said you or Boris or 3 cell have to believe. Maybe be a little more tolerant would be wise .
You believe in abiogenesis and thats fine and your right to . Just as its marks to believe what he wishes .
