I could come up with a number and stick to it, and dare anyone to prove me wrong :).You could, but then you'd be buying into a pointless "how many angels can dance on a pinpoint" style argument where I get to say "prove it" endlessly to keep you on the defensive.
Don't worry, I won't present your non-answer as a "proof" that your scientific beliefs have no merit ;-)
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
