Yes so you know anyone with a grade 10 or higher should be able to comprehend what you say.
My 11 is:
You are making two conceptual errors here. The first is that you can make a calculation when you only know part of the possibilities and have no idea how large the set is. It's not a probability, it is just an opinion based on your world view of what you think the probability is: there is no calculation. This pseudo-probability argument is just the argument from incredulity dressed up.
