What if WE as humans are the building blocks to something bigger?

Philosophically, this is a nice discussion, but biologically, it isn't all that attractive. For one, we just have no evidence to support the idea that there is anything more complex that makes up the quark, for example. So our understanding, with loads of evidence up to this point, has the atom, the molecule, then compounds, etc in the level of complexity. It is an interesting concept that the earth is merely a particle in something bigger, but the interaction of that particle and the role it plays, are complete unknowns to us, and completely unsubstantiated by our study of the planets and galaxies around us.
