@Rajashree,
Honestly, I am uncertain how far we can actually take it.
This is from wiki:
In quantum mechanics, wave function collapse is the phenomenon in which a wave function—initially in a superposition of several different possible eigenstates—appears to reduce to a single one of those states after interaction with an observer. In simplified terms, it is the reduction of the physical possibilities into a single possibility as seen by an observer.
The way I understand it, physical matter is superpositions that are reduced to a definite state, something that apparently requires an audience to happen.
Which raises the question of how physical matter could happen so that there was something for life to happen with, and somewhere for consciousness to grow, resulting in conscious observers.
It is not an overly troublesome issue, but I think its very entertaining to think on it.
