I figured that out, actually.
God created mosquitoes to be food for bats.
satan corrupted the mosquitoes, so that they’d have to bite man (God’s favorite creation), and cause disease in the same creation (man).
satan cannot create anything on his own - he takes something pure of God’s, and distorts it for his evil purposes.
Then the question is why the BAT? One created for the other? hahahahahaha. What good did that accomplish?
Oh well, one day we will know.
