Sure, just go outside and look around. The lights from space are called stars and the moon. This is pretty basic stuff.

I assume you mean, could we see the dark side of the Earth by shining a light on it? The answer to that is, yes. The moon does that for us on a regular basis, but very dimly. Otherwise, to see it as we see the lighted side we would need to aim a light at it with the same number of lumens as strike the lighted side and that would require a light source of extreme power. It would result in a horrendous light bill.

The Earth Can be observed at night by infrared radiation from the earth by satelites.
The light from star falling on the Earth is only 1.1 x10^-11 joules per steradiants per seconds. Its not sufficient energy to make it visible from other location in space.
