Invalid science

Invalid science is like a pretend game where you make up rules that don't make sense. Just like how you can't say that the sky is purple without any good reasons, scientists can't say that a certain idea is true without doing experiments and collecting evidence to prove it. If a scientist makes up a conclusion without any real evidence or makes mistakes in their experiments, then their conclusions are not reliable and can't be trusted. It's like saying you won a game even though you never played it, it just doesn't make sense. Invalid science is like playing pretend with no rules or making things up that aren't true.
