tbree - hate to be “that guy” but I gotta correct you. While you are right that the matter on earth came from other places and was likely the result of an explosion (maybe a supernova, who knows, not really sure) the “molecules in your body” were not formed at that time, and many didn’t even exist as the MOLECULES they are currently until they formed inside your body from other ATOMS.
Futhermore, heat/temperature of something is a function of how actively the molecules of which it consists are moving and bumping into one another, therefore a molecule, in and of itself, is neither hot nor cold.
