Any ideas why most children have primary brain tumors and why do most adults have secondary brain tumors?

In brief: Simply age

Cancer is very rare in children, and relatively common in adults.
So children rarely have a "chance" to have a cancer elsewhere in the body which can spread to the brain, whereas adults have plenty of chances to acquire secondary brain tumors.
