Yes, I did, I stated what we can scientifically prove, and what we surmise based on observation.
However, the Earth when it was being formed CAN'T be observed. So, we have to make educated guesses based on physics, and geologic processes that exist now.
I can tell you without reservation that starting 4.2 billion years or so ago, the Earth began behaving like it does now.
I CAN'T tell you what it was like as it was forming, or for about 100 million years afterwards. We simply don't know. But we are honest enough to admit it.
