1. If the Moon existed before people, then Idealism is false.
2. The Moon existed before people.
Therefore, 3, Idealism is false.
I'm asking for which premise in particular is false, or why the argument is invalid.
(1) is false, or at least questionable, because it depends a further argument, namely, that mind is something that only exists by virtue of the evolution of H Sapiens.
But I don't think you will find, anywhere in the writings of various forms of idealism, the statement that 'idealism consists of the belief that reality is all in the human mind'. Idealist philosophy generally understands 'mind' in a different way. For that matter, so does phenomenology and 'embodied cognition'. None of them have a representationalist model of consciousness.
I do understand the difficulty inherent in this question, which is that you are starting from the assumption that mind is the byproduct of brain (which has been discussed ad infinitum in other threads).
Of course it is dead simple if you adopt the argument that H Sapiens just happened to evolve and the brain just happened to develop in such a way that it appears to produce a mind. Within this framework the basic notions of idealism are completely unintelligible. But I find traditional Western philosophy asks questions which that narrative has no answer for.
I don't know if that will help but at least I am trying to answer the question directly.
