Let's say aliens visited in the past few million years of Earth.
An intelligent species had not evolved yet.
Let's say the aliens wanted to leave proof of their existence, in case an intelligent species ever evolved here.
Where would said aliens put evidence of themselves, that would last millions of years?
no ideas?

On the moon I guess. If an intelligent species would evolve it would be very likely that it would go there when it is able to.
