Direct and indirect evidence in science

Hi, couldn't find a place to post these questions so decided to try and start a new topic:What is the definition of direct evidence and indirect evidence and could you please provide examples of each? In relation to evolution, would the fossil record be an example of direct or indirect evidence of evolution?Also, could you explain why indirect evidence is "good enough" evidence to support scientific theories, or provide examples of commonly accepted scientific theories, where supporting evidence is wholely, or mostly indirect? I know atoms are at least one such theory (source: Questions and Answers - What is one example of indirect evidence that scientists use to study an atom?)Currently debating a creationist and he's been nagging me about evolution only being supported by indirect evidence while every other scientific theory is apparently supported by direct evidence...didn't want to state any falsehoods which is why I'm asking
