Helicocentric Flaws

So u mean to say for the moon to be revolving around the sun it has to speed up to catch up to the earth cuz earth is moving, which totally defies the gravatational pull from the earth to keep it in orbit I can understand why satellites float because they are too small for gravitational pull but the moon is large enough to have gradations pull from the earth just like how it pulls back an gives us tide. but wait a minute if both are pulling why aren't we crushed as yet.Do these flat earthers have a point ?
