Title: The Last Signal: Humanity Declared Extinct — A Documentary

Humanity is gone — but one strange transmission changes everything. "The Last Signal" is a cinematic documentary-style short for HFY Sci‑Fi that follows the discovery of Signal A: a repeating, artificial tone found the night the last humans vanished. Scientists, archivists, and leaders race to decode its meaning while the galaxy listens. Was it a memory, a warning, or a trap? From empty city streets and forgotten keepsakes to labs chasing code and councils choosing whether to reply, this film asks one simple, haunting question: if a species disappears, who speaks for them — and who will remember?

Watch as we explore:
• The final days of human civilization and the small traces left behind
• The mystery of Signal A: waveform, spectrograms, and a single decoded word — REMEMBER
• The global debate: suppress, archive, or answer the transmission
• The Offering: a curated human archive sent into deep space
• The aftermath: responses, guardianship, and the quiet hope of being remembered
