It is a kind of confusion, isn't it? I just looked it up in the Collins dictionary and Google dictionary. "evidence" is a singular noun with different meanings.
- N-UNCOUNT Evidence is anything that you see, experience, read, or are told that causes you to believe that something is true or has really happened. (Example sentence: Ganley said he'd seen no evidence of widespread fraud.)
- N-UNCOUNT Evidence is the information that is used in a court of law to try to prove something. Evidence is obtained from documents, objects, or witnesses. (The evidence against him was purely circumstantial.)
You can also "little evidence", and more as follows:
ADJ. abundant, ample, considerable, extensive, plentiful, substantial, widespread | growing | clear, compelling, conclusive, convincing, decisive, good, hard, incontrovertible, irrefutable, overwhelming, persuasive, positive, powerful, solid, striking, strong, unambiguous, unequivocal | adequate | flimsy, inadequate, insufficient, scant | concrete, direct, firm, first-hand, objective, tangible The figures provide concrete evidence of the bank's claim to provide the best service
