I'm not sure that our words/actions/moods affect the quantum world (a strange construct) in anything other than a gross way. I can move a glass of water with my mind: First, I decide to move the glass, then 2) I take my hand and move the glass. I have moved the glass with my mind and every quantum thing associated with that glass has been affected. Big Deal.
What we would need to demonstrate to make your first statement interesting is the ability to affect something at a sub-atomic level in some measurable way with just our thoughts with no mediators such as a hand. Also, no cheating by saying that the electrical reaction in our brain affect the sub-atomic simply because thinking is electrical.
Now supposing the hypothetical: If in fact science were able to detect such effects and somehow infer correctly (I wouldn't know how) that there was a "being" behind it, then just the fact that they could do that would perhaps admit of the idea that we could interact. Interestingly, detecting actions at this level would suggest the possibility that we could intentionally act at a quantum level. Seems to me, we just made ourselves gods -- at least, of the sort in the hypothetical.
