Do you think about the concept of reality and the fallacies that time and space even could exist?
i think the word 'exist' was born within time and space. so i think it's fine to say time and space exist. if you say it doesn't, then you'd have to say nothing does. but then why do we have the word...... if you want to say time and space doesn't "exist", then i think you'd need to graduate to a broader concept, other than 'exist'. because 'exist' already has a well established meaning within our world, and to suddenly change that to render the word totally meaningless would be a bit sneaky
