The fact that the world existed before awareness existed prove that this is not so.
according to Idealism, awareness is fundamental - and the world is the activity of awareness, and if the case, the 'fact' above is not true.
Rabbit hole alert! Before we descend, discussing mind and reality requires definitions. This topic usually goes into 50 pages of nonsense whenever it pops up. If we go there, I'd heartily recommend first agreeing on definitions. Here are some for starters:
OR: objective reality: includes agents and environs (external to agents), consensually described and determined, not in doubt, no indication agents must be here for OR to exist, it's where we do our science
SR: subjective reality: internal experiential existence, as described by agents
MDR: mind-dependent reality: term used not to question the existence of OR, but to indicate the limitations of agents in dealing with it. This is why our view and understanding of OR can change over time, without changing the source facts. MDR is a description of the nature of knowledge, not the cosmos.
MIR: mind-independent reality: easily confused with Objective Reality, this term was coined really to contrast with the prior definition above, not to contradict the idea of Objective Reality. Highly recommended to spend time thinking about this term, and what it means, before use.
To save time, we could avoid all this by simply recognizing that MIR, "mind-independent reality," is an oxymoron for agents. OR is not under 'attack,' the cosmos does not need agents to exist, and science works as always.
It is just that agents process OR as MDR, and no agent can directly 'grok' MIR, by definition. The cosmos is safe, and does not need us to be.
