Step-by-step explanation:
Evidence is a very important part of a logical argument's persuasion as it is the most meticulous to gather and most irrefutable. Evidence is the basis of irrefutable claims of facts and logic that can be built upon it.
Evidence can be of many types.
It can be scientific or based in the findings of a science like the forensics to prove a crime or the evidence of existence of some phenomenon in space explaining something we see in the night sky.
It can also be evidence from proof or even substantial or testimonial depending on what sort of evidence is required.
