No evasion. The premise for your examples didn't apply. I don't like snakes, period, and the only acids i consume are the ones in food products. For whatever reason, I've never felt the need to consume e.g. hydrochloric or sulphuric acid.
How are you defining truths? Something that is factual and verifiable by anyone, such as a claim that Theresa May is the Prime Minister?
since you are into the answer a question with a question routine, I'll ask you what
you think is a scientific truth.
As is often said on these boards, science never says it can 100% prove anything, but the Theories they have, for instance that the earth goes round the sun, are as near 100% as possible while remaining open to challenges and improved information.
