You just said it had been falsified by "basic observations from Physics and Chemistry"
Indeed.
it can't be unfalsifiable and falsified.
If someone has a hypothesis, it should be falsifiable. However when the things that falsify it are thrown out using philosophical arguments such as the NPF, argument from incredulity, etc., then the net affect is that the hypothesis is to all intents and purposes, unfalsifable.
Another example of the above is the kind of atheism implemented by some on this forum. It is not merely an absence of belief, otherwise those holding such views (particularly those who have clocked up years posting on forums) would be able to state what would falsify (i.e. change) their position. It, on the one hand wants to maintain a positive stance, while giving the appearance of being something completely different.
What is the hypothesis you are referring to?
That consciousness can come from non-consciousness (or intelligence from non-intelligence)
