Just a bit confusing about the energy-beings thing (i think it's plausible but i got a bit confused with the definitions)
Energy: In physics and other sciences, energy (from the Greek ενεργός, energos, "active, working")[1] is a scalar physical quantity that is a property of objects and systems which is conserved by nature. Energy is often defined as the capacity to do work. Several different forms of energy, such as kinetic, potential, thermal, electromagnetic, chemical, nuclear, and mass have been defined to explain all known natural phenomena.
Then, like it was said already, we are all already energy beings after all.
Now, the definition of life is far more complex than that, and since there is no unified consensus on what life is whatsoever makes it all more hard to explain... by some definitions we could say that supernova stars are alive since they give birth to several new stars and we could call that reproduction...
Now for it to be intelligent is another business, we humans almost didn't made the jump into intelligence, it's believed that we became intelligent thanks to spare time to use our brains on something else than survival itself; and that could have happened to any other species!
I think it's not too hard to believe there might be other intelligent species out there, made of whatever material they might be, and whatever structure they are shaped from. Life has proven to be more stubborn than what we believe...
(phew, that was a long post, i hope it made some sense at all
