Actually yes, particles can appear out of nothing. At the tiniest scales, energy acts randomly and something can ever-so-briefly appear from nothing. I am not saying this randomly (out of nothing... ). Late Stephen Hawking said in his book "Brief Answers To Big Questions". He called the universe "the ultimate free lunch" because it came into being on a minuscule scale out of nothingness with no cause or creator beyond the laws of quantum mechanics, which allows for randomness

Not to be rude, but this makes up no logic. Assuming 'came out of nowhere' doesn't makes any sense. There has be a source and my answer somehow manages to demonstrate what could it be. Quantum mechanics are not fully understood due to its inter-dimensional properties and that is why, they're very complex. Even properties has to be originated from something before nothing. And that something is beyond Human's ability to think. Still, many logical ideas with logical proofs have come up.
