Fluorine Form Molecules or Crystal lattices or exist as a single atom.
All elements and all compounds do not exist as molecules. As examples, noble gases exist as individulal atoms and ionic compounds form lattices.
Halogens are considered to be diatomic molecules. They exist in gas (F2, Cl2), liquid (Br2) and solid phase (Iodine I2).
Hydrogen molecules do exist (as H2); this is how hydrogen is found in nature.

a molecules are made of atoms
There are quite a few molecules that must form for life to exist. One of these life-supporting molecules is water.
The were not invented, they exist. Atoms and molecules were discovered.
no
Ozone exists as triatomic molecules. O3

Hydrogen molecules do exist (as H2); this is how hydrogen is found in nature.
They have completely filled valence electrons, hence are stable, chemically inert. So they exist as mono atomic species and not as molecules
