I am having trouble with this one question. Please help? (:
Explain why Earth and other planets were not solid when they formed during the beginning of the Precambrian, approximately 4,600 million years ago (MYA)

The earth is NOT solid, even now. We live on a thin crust under which is a molten mass of liquid rock several thousand miles thick. I do not think there are ANY truly solid planets in our solar system. We're not 100% sure of course, since we have not actually been to any of them.
@Melissa bowers. You're plagiarizing. These aren't even your answers.
If you guys are still looking for answers if you go to part 1 of the question there is a link that you use to find the answer.I hope this helped :)
Because collisions between large planetesimals release a lot of heat, the Earth and other planets would have been molten.

The earth was not solid because it was dust, probably from a super nova. This time period is called the Hadean time period the reason it is not considered part of earths geological history is because the earth was not done forming in the Hadean period so there was no rocks to measure the age of the rock.
What they were trying to say is that we think earth was brought in differently than science does we think god made earth scientist think it was dust coming together
