Why is Earth so much larger than everything?

I have been wondering, why is Earth so much larger than the moon the sun and every thing else? in RE the sun is 1 million times larger, so why so small in FE? Also, I read a post saying that the other bodies in space are made of lighter materials, why would they?

Think about it like this:

If it were common knowledge that the earth is flat, and a small group of people were trying to prove it was round, the FEers would say, "Why is everything so much larger than the earth on your model? Why is the sun so big? In FE it is much smaller, why isn't it in RE?"

Well handled, taters.

Thats true, thanks for the answer. But in RE that can be atributed to other planets/stars starting mass. if a planet by random smashes into another, it will get larger, then attract more mass to itself.

Also, Earth is larger by a large degree over Mercury,Venus,Mars and every moon. it's even larger than some observed neutron stars.
