Not sure why this thread from 2005 was resurrected, but please read the FAQ thread in the General Physics forum.

No that's not true. You cannot create something from nothing. Something has to exist prior to creation of something else otherwise where would the causes for new phenomena come from?
I fully agree!

We had this discussion a couple of times and I can only repeat what I stated before: Even for virtual particles energy conservation holds at every vertex in a Feynman diagram!
