we see light because

Light, unless reflected/scattered of something can’t be seen. The sky
is blue because of scattering of the suns rays by the earth’s
atmosphere.
You see any object when light hits that object and is reflected back.
We can’t see glass since it lets light through, we can’t see a black
hole since it doesn’t reflect the light that is falling on it.
In laser guided bombs, the detector/photoreceptor sees the laser
reflected from the target on which the laser beam is aimed.
All this means that the photons are being reflected of objects,
scattered by air.

What if it was possible to see the point of light, just a point, not
the beam, without needing anything for reflecting the beam/photons
back.
What would be the use of such an invention?
