Q: Do you believe in evolution? Give evidences in favour of the theory?

what should be the answer of first part of question here? if i say 'NO' but later on i provide evidences that YES it occurred (as one has to mention due to the nature of the question). what would have been the impact on examiner?

if u say YES then you have to support and vice versa.

In both senses u should have to explain why u agree or disagree..
