What about it? It's religion. It's not science.
And what scientists would that be? Certainly not cellular biologists.
Let's just assume that without naming any scientists in particular that you are a big fat liar.
Intelligent design is the only choice for someone who puts not value in scientific research, but prefers child molesters and con men to educate them in the workings of the world.
You don't even understand what evolution is. Evolution began when time began. It's not limited to biological entities. Evolution is change over time, whether in organisms or molecules.
Interactions between elements on the surface of the cooling earth led to the formation of simple molecules, which in time led to the formation of more complex molecules, some of which were stable and continued to exist, while others were unstable and had a brief existence. Those molecules which lasted in turn gained additional information by interaction with other molecules.
You're likely trying to say "Scientists don't know how life on Earth began! They don't have proof!"
No, they can only extrapolate from the data they have, such as molecular complexity, the formation of amino acids, experiments in proteins and enzymes, environmental factors, etc. The higher probability lies with a natural event, but they can not discount the possibility of life coming from offworld in the form of a single cell organism in a meteorite, or even a seeding program by a theoretical offworld life form. They do not state that any potentiality is the absolute truth because there isn't enough data to make a claim yet.
Unlike intelligent design, which says "God did it. Yes, God. What are you talking about, proof? It's God! God doesn't need proof! Look, a duck! Can't you see the god?! It's right there, in the duckiness of the thing! No no, put down that microscope! DNA proves nothing! Endogenous Retroviruses? What are those? We don't know what they are so they must not be relevant! God God God! La La La I can't hear you unless you're praying to Kent Hovind's wallet!"
