When did evolution become a fact and not a theory?
It’s a theory because it can’t be proven, but that doesn’t mean it can’t be generally accepted as fact. It’s strength is that it can continually be tested and not contradict itself. Even if one is unwilling to accept evolution as fact, it must be accepted that it is the best explanation of life that we currently have. The reason it is generally accepted as fact is because recently it has been heavily debated (especially by religious groups) and in the face of such criticism, the concepts still hold water.
There are thousands of pieces of scientific data supporting Evolution. The logic of it is quite simple and complex and beautiful. Given enough time, anywhere in this Universe, matter will evolve into consciousness. We did evolve from molecules but we are also made of molecules. We are a billion billion atoms. And those atoms are made on the insides of stars.
