I tower over the man-made plain;
My peaks scrape the heavens.
I have many brothers; in fact,
We may be as many as a hundred and seven.
We're as ancient as the oldest trees,
But not older than the hills.
We've been studied for centuries now,
But with mystery we're still filled.
The pyramids of Egypt.
What starts with a P and ends with an E and has a thousand letters in it?
