I am tempted to answer "because that is the way DOWN and UP are defined"!

If you stop and think about it, the only definition we have for "down" IS the direction gravity pulls things!

You probably want, however, the fact that gravity always attracts and so the earth's gravity pulls thing toward it- down.
