There is a very simple test to determine if a person is proselytizing to you
or attempting to teach you about objective scientific truth: statements made
by proselytizers cannot be verified by empirical observation. Scientists
sometimes disagree about which theory best explains the empirical evidence,
but no scientist denies that true statements about reality are
evidence-based.

The statement "Paleolithic people did not use electricity" is a factual
statement of science. The truth of the statement can be verified by
examining the overwhelming physical evidence of its truth left behind by
primitive peoples.

The statement "Those who live without electricity live closer to God" is a
statement of religion. It is a value statement rather than a factual
statement. It cannot be verified empirically. The person who makes such
statements in hopes of convincing others of its truth is proselytizing
rather than teaching scientific truth.
