If I do not, is that reason to mock me?
It is, at the very least, a reason to educate you.
Of course, one can only educate people who want to be educated.
I have no problems mocking grown ups who are willfully ignorant
I do not, however, mock children.
There is also the distinction that while people should receive a minimum of respect, the same is not true of ideas.
Ideas should stand or fall on their own merits, and they should be ruthlessly examined, criticised and demolished if they do not hold up to scruteny.
How do we observe allele? Is it as simple / accessible as watching a rock fall to ground?
It is at least not terribly difficult and you need no special education and/or access to fancy equipment to do so.
I'm assuming at this point that you know what alleles are and what they do (if not, let me know and I will be happy to explain), so for instance, the change in frequency in the population of, say, people with blue eyes would constitute a change in allele frequency. It's really that simple.
And what might be example of things that don't change over time? (To my mind comes answer of 'speed of light' but not sure if that is a thing.)
The laws of physics appear to be, if not absolutely constant, then at least very very consistent. As we know from Einstein's work, they change under certain specialised circumstances (but in a predictable way) and they also 'switch' when going to subatomic levels, where Quantum Theory takes over from Relativity.
Also if we are making any sort of predictions about changes over time, how is this not scientific theory? When does observing allele stop being fact and start being scientific process (theory)?
The level of Scientific Theory is the highest level of explanation we have about an aspect of the Universe, be it germs and disease (Germ Theory), atoms and atomic bindings (Atomic Theory), gravity (The Theory of Gravity) or the development and diversity (but not the origin) of living things (The Theory of Evolution).
This means that a Scientific Theory has to take into account all the facts, observations, evidence and laws included in that aspect of our understanding of the Universe. It is, if you like, the box into which all of these things have to fit. And if it doesn't fit we have to either modify the box so that it conforms to the data we have, or change it altogether for a better box.
So when we say that Evolution is both a Theory and a Fact, we mean exactly that, and the same goes for, for instance, Gravity. Both terms apply both to a Scientific Theory AND to an Observable Fact.
