Or if there is even enough of those elements accessible near the surface crust to make technologically advanced civilisation possible.
Given the circumstances that led to the creation of the moon, I wonder if there are any earth-like planets (chemical composition wise) out there at all.

Your first comment re the moon is still being debated and there some heavy elements on the moon
Just based on sheer numbers there has to be another earth like planet out there. At what stage it is at or whether it has life, who knows but the odds are it exists.
Again, you are assuming that the life form will require similar conditions to ourselves. In a hotter environment Silicon could be the base rather than Carbon for a life form, look at the periodic table and you will see why.
Keep your minds open, there is more to this universe than we can imagine yet.
