The purpose was to make a crater to excavate the material and see what was underneath the surface of this comet, which we learned quite a bit about.

When we then find something very important, like the bones of a human ancestor, we begin to excavate it extremely carefully and slowly, using dental picks and fine paintbrushes.

An option may be to excavate the site and conserve the remains with soil or a special covering afterwards, so that the construction can occur on top of it.

To be able to excavate the 80 tons of dinosaurs that we have in the Sahara and take them out, you really have to put together an expedition team that can handle the conditions.
