according to quantum physics, why do some scientists say that light could very well be a living thing?

I’ve never heard anyone say that. There’s no reason to think that small energy packets are alive. And there’s nothing in quantum mechanics that would suggest that. Are you sure you’re not misunderstanding something?

Never heard of that. Could you refer me your source?
PS
Itsd been a day and still NO reply from the questioner as to where he heard that story. Has he been listening to George Nouri’s late night AM radio show?

I’d never heard this, but it sounds interesting. Could you provide some links?
