A fact is an observable reality, something that can be quantified or measured, or God’s Inerrant Truth as revealed through the Bible.
Examples:
* The table is made of wood.
* Washington DC is the capital of the USA.
* Water freezes at 32 degrees F.
* Jesus died to take away all our sins.
* God created the world and all life in seven 24-hour days, less than 10 thousand years ago.
An opinion is a matter of taste, a view or judgement about which people might reasonably disagree, or a “scientific” claim that contradicts Biblical truth.
Examples:
* Blue is prettier than yellow.
* My mom bakes the best chocolate chip cookies in town.
* Mr. Jones is a better candidate for Mayor than Mr. Smith.
* The Universe is several billion years old.
* Humans evolved from apes.
