MAC!! You continue to surprise me.

You're right on many counts: It took about 2000 years and the assault of

skepticism (everything can be doubted, there is no knowledge; how do you know that you're not in The Matrix, lying in a nutrient filled bath with a virtual reality being pumped into your brain?)

Skepticism brought forth Descartes to ask, "Is there anything I cannot doubt." His answer was "when I am doubting something, I know that I'm doubting it." So, there is at least one thing Descartes thought could be know for certain. Actually, his conclusion was too strong because he inserts the presence of an "I" - a self. What he was entitled to know was that something was doubting.

Here's a little thought experiment for everyone to consider:

You forgot your watch at home and you're walking past an atomic clock that indicates it is exactly 2 o'clock. In fact, at that moment it is 2 o'clock, exactly. There are no tricks in this experiment. Now, do you know that it's two o'clock?

And, oh yeah, it is a nice tune. Thanks.
