Most of the time, humans don't know what they are talking about. Belief is the fundamental way for humans to get to a truth of any kind. It is so because humans lack the capability to reach truths by means of evidence. For example, covid-19 death tolls have been listed on a daily basis for more than 2 years now, that is, 2x365= 730 days. Which day's figure was ever made evident to you. To the mass majority, it's zero. You have zero evidence on any 1 day's data out of the 730 days of data. The figures are conveyed in a form of human testimonies from those who are responsible for counting and collecting the data. Their number is in a negligible amount, the rest of humankind needs to believe either their testimony (i.e., their data gathered) is accurate or not. The mass majority won't (i.e., will never) have the evidence anyway, since it's not possible and incapable for them to get to the evidence directly.
Either you believe those figures or you don't. It is completely out of human capability for each and every individual to acquire evidence by digging into the details such as the name list of the dead daily and how each one died specifically.
In a nutshell and in today's world, you believe everything by putting faith in the credibility of the mass media to get to truths of any kind. You don't dig and examine the evidence. Instead, you are sitting home to get to the truths by means of BELIEF! Evidence belongs to the eyewitnesses whose number is very few.
Well, President Trump often warned that "You are fake news".
He questioned the credibility of our media while evidence is never part of the formula.
And you know that God exists simply by watching humans farting nonsense.
All you need is faith, that's what God said. Apparently, God knows better.
