Evidence of absence is not "We've looked here and there and have not seen anything, therefore it doesn't exist"
An evidence of absence argument would be things like "We know that rubber wasn't invented until the late 1800s/early 1900s (or whenever it was invented) and there is no examples in the archaeological record of rubber during the paleolithic, all evidence of tools made in that time period were made from stone and wood, therefore it is reasonable to conclude that rubber was not invented in the paleolithic era and therefore did not exist". That would be properly supporting the argument from lack of evidence. It also leaves open room that you could be wrong.

A non fallacious argument from evidence of absence includes positive evidence, as this example shows

This is the argument from ignorance fallacy. I called it silence earlier, and that's an alternative name for it, but that can also be confused with another fallacy also named argument from silence, so as to avoid confusion I'll point this out hereExample, there were no rubber duckies in the Paleolithic period. My test is we have not found any rubber duckies, so until we find one rubber duck, my statement is true.

Evidence of absence is evidence of any kind that suggests something is missing or that it does not exist. For example:
If Alice bakes a pie, she then places the pie on her window-sill.
She did not place a pie on her window-sill.
Therefore, Alice did not bake a pie.
Since it necessarily follows from the first premise that Alice will place the pie on her window-sill every time she bakes one, upon observing that there is in fact no pie on the window-sill, we can deduce that Alice did not bake a pie. This argument is called modus tollens in propositional logic, and is written in sequent notation in this manner:
P ? Q, ?Q ? ?P
Per the traditional aphorism, "absence of evidence is not evidence of absence", positive evidence of this kind is distinct from a lack of evidence or ignorance[1] of that which should have been found already, had it existed.[2] In this regard Irving Copi writes:
In some circumstances it can be safely assumed that if a certain event had occurred, evidence of it could be discovered by qualified investigators. In such circumstances it is perfectly reasonable to take the absence of proof of its occurrence as positive proof of its non-occurrence.
