"(1) We can't be 100% sure of anything. Did evolution happen? Almost certainly. But nothing's 100%. To dispute the uncertainty of our knowledge is ridiculous. Are you even 100% sure that the sun will rise tomorrow? Then you are arrogant or ignorant."
This is an accurate statement because the sun will not rise tomorrow. That is just a subjective way of stating how our position on earth appears in relation to the sun from our point of view. It is acceptable for everyday speech, but if we are to use this as an example of the unreliability of fact, it is important to accurately describe what we are saying.
The fact is the sun does not rise. The earth, which we now know to be spherical, will continue to turn until the bit we live on faces the sun again. I am 99.9999999999 certain that the earth will complete its rotation every 24 hour for many years to come.
I realize that being so pedantic makes me sound like a smart-ass but it illustrates the need to be precise in matters of science. The USA was able to land Neil Armstrong on the moon because they accurately understood the precise mathematics of the task they attempted. On occasion they have got their sums wrong, with tragic consequences. Science and engineering nowadays is a very precise business. Guesswork is not acceptable.
