What evidence from Blade Runner supports Deckard being a replicant?

I just rewatched the original Blade Runner and I’m genuinely stuck on whether Deckard is a replicant or not. The clues seem to point that way, but the ambiguity feels so intentional it makes my head spin. I’d love to hear what others think based on the film’s own evidence.

Last time I watched it I kept circling back to the unicorn moment. Gaff's origami, the unicorn motif in the dreamlike hints, and the way the city hides things in plain sight felt like a pattern more than a hard clue about truth. It seems the film tests your patience with ambiguity rather than handing a verdict. I left with the sense that the clues point in both directions and you’re supposed to decide what it means for yourself.

Honestly the more I rewatch, the less confident I am about anything concrete. The Voight-Kampff test exists, Deckard's reactions feel calibrated, Tyrell's charm feels omniscient, and yet the film never seals them as proof one way or another. I used to chase a single line of evidence, now I just note how it makes me check the next scene for a counterpoint.

I tried to map the timeline and the character cues: his weariness, the way he sizes up Roy, the tenderness that pops up in rescue scenes. It can read as a human still hurting, or as someone who knows more than he admits. I paused, checked a few things, and I still walked away without a clean answer.

One thought that keeps nagging me and might be off base: maybe the real issue isn't Deckard's nature but how the film treats memory as identity. If he's human, memory still matters; if he's a replicant, memory becomes a crafted comfort. Is that the real problem?
