Is it remotely possible that there was an advanced civilization on Earth preceding the earliest "known" organisms?

Keep in mind that the Earth is roughly 4.5 billion years old. Until about 3.9 billion years ago the earth underwent the late heavy bombardment - a period where asteroid and comet impacts of high frequency and magnitude occurred.  There is solid evidence that the crust of the earth was shattered and reformed repeatedly during this time. No large scale geological formations have been found that are dated more that 3.8 billion years old for this reason.

Discarding any truly baseless theories of earth's early geological history, there is no possibility that an advanced civilization could have emerged in such a short and violent period.

Cheers.
