Scientist that say it need liquid water to create life miss imagination.

Like water (which floats on water), few substances expand upon freezing, meaning they are lighter (less dense) in their solid state than in their liquid state.
The best-known examples, besides water, are:
Gallium: A metal that melts just above room temperature. Solid gallium is less dense than liquid gallium.
Bismuth: A metal that expands upon solidification.
Silicon: Exhibits this property, especially in specific crystal structures.
Geranium & Antimony: Similar metals/semimetals that expand upon solidification.
Acetic acid (in its pure form): Sometimes also referred to as a substance that becomes less dense in its solid state.
