In ancient times, when some cultures started using explosives, they used some on the fields. This was seen by others and at first it was said to be magic. Later on they realized it was not.
The whole idea behind what I said is that, while now, for us, the idea of a soul might seem like "magic", it may actually be true and be something we don't fully understand yet. Dismissing the idea from the start is ignorant and close-minded.
And by the way, this is not some random scientists nobody knows about talking about stuff that comes out of their ass. That's why I linked their wiki since I knew people would think that and they'd be too lazy to google them. Penrose had some of his theories expanded by Hawkins even. And no, he's not doing this because he's super religious, he's actually an atheist.
Hameroff is a professor and reknowned for his theories on the consciousness.
They both had numerous awards, and quite important ones too.
Not saying they can't be wrong, but I'm saying you should think more before saying "oh, they're stupid" when both have studied in the field of the theory far more then some of you have lived.
