Could the Titan moon be a wake-up call about our biological ignorance and exoplanet fashion despair?

Far as we know (which is very little), Titan doesn't harbor life (the life we know), but has two strong (Earth Life) biosignatures N2 98% and CH4 2%. As far as we know, abiotic processes occurred...
