Religion refuses to do this.
Most of humanity refuses to do this.
The initial chapter to Penn Jillette's book on religion [and on his atheism] highlights that three of the most important words in the English language, and three that are REALLY phenomenally difficult for most people to say, are "I don't know."
People treat it as an acknowledgement of failure to respond to a question with "I don't know", so they respond with what they think they know, which so often just ain't so.
That is a trait of humanity, not of religion -- albeit part of humanity from an early stage was to ascribe that which we don't know to the supernatural, i.e. religion.

Science NEVER claims to state truths, just reports on the current likelihood based on the available evidence. Emphasis on CURRENT, LIKELIHOOD, and AVAILABLE.
The problem is when journalists start paraphrasing scientists and confusing science with speculation.
Yes. The issue is not with the science, it's that people who don't understand the nuance want to treat everything in a world of white and black, and so they use simple [and wrong] shorthand for "the science".
When you hear a scientist, or an engineer, or a doctor, or many other professions give an opinion on something in their field of expertise, usually anything they say is going to be very carefully phrased to identify the limits of that opinion, and often with a given confidence level.
