To more fully address your point, I've thought about this same sort of thing. What I came up with is that the universe began with a "big boom" where a quantum singularity expanded rapidly to form the universe. Some theoretical physicists believe the universe will eventually collapse back onto itself forming a new quantum singularity from whence a new big bang can occur. Repeat this ad nauseaum and eventually all the atoms that make us up will eventually form something else, maybe a chair or a rock or an apple or a fire ant. Perhaps the atoms that are now in you and in that fire ant once made up something else, which is why you feel that connection.
