Why is it hard for a program to generate random numbers?

Question

My kids asked me this question and I couldn\'t really give a concise, understandable explanation.

So I\'m hoping someone on SO can.

Answer 1

Because there is no such thing as a random number.

Random is a human concept that we use when we cannot comprehend data and do not understand it. If we are to believe that science will ultimately lead to an understanding of how everything works then surely everything is deterministic.

Take away the human and there is no random there is only "this". It happens because it happens, not because it is random.
