Actually, what physics (not necessarily quantum mechanics) tells us is more like this:
'A tree falls in the forest.' Meaning, some redisposition of matter and energy occurs within a certain set of spatiotemporal coordinates. If you
were there to see it, it would look and sound exactly like a tree falling in a forest (because that is exactly what it is). If a bat were observing it
instead, the bat would see and hear something which, if it were played back to you, would
not look and sound like a tree falling in a forest.
That's because a bat's senses and brain are different from yours. You wouldn't recognize what it sees and hears as anything familiar to you at all,
but the bat would hear and see what sounds and looks exactly like a tree falling in a forest sounds and looks like... to a bat.
If an alien were present that had senses that saw microwaves, or felt sound as heat, then that alien would perceive whatever its senses were evolved
(or designed) to perceive. Again, it would make no sense to you if you 'saw' or 'felt' it, but it would still be what a tree falling in the forest
'seems like' to that alien.
What actually happens in the forest is a dance of subatomic particles, of energy transfers between them through the exchange of virtual particles.
That dance, that transfer through exchange, will occur whether you, a bat or an alien are around to see it or not. The appearance it takes when one of
you is around to watch it will depend on which of you is watching. In each case that appearance will differ. But the underlying phenomenon still
occurs, whether someone is there to give form to it by watching it, or not.
We see the world through senses and brains designed to interpret the dance of phenomena in certain preset ways. This is not an illusion, and it
certainly does not mean that consciousness creates the world. The tree falls in the forest whether or not anyone is around to observe it--but it only
looks like a tree falling in the forest if someone is.
