When God made man, He put everyone who was to be born into Adam. We come out of Adam. Hebrews 7 shows us this truth. Verse ten speaks of how Levi was still in the body of his ancestor Abraham, when Abraham met Melchizedek. What's even more exciting and profound than this, is that we all came from heaven. This is why heaven is our home. 1Peter 1:3 tells us how God has once again become our Father through faith in Christ.
Blessed be the God and Father of our Lord Jesus Christ, who according to His abundant mercy has begotten us again to a living hope through the resurrection of Jesus Christ from the dead - 1Peter 1:3
