How are we able to see objects if they don't emit light

normal objects don't emit light, you see the light reflected off of them. for example, when you look at a banana all colours in the visible spectrum are absorbed except yellow, which is reflected back to our eyes.

the sun, light bulbs etc emit light, but staring at them isn't advised.

if you mean different shades of light in the spectrum that we can't see with human eyes then that becomes trickier. things like xray, ultraviolet and infrared are well-known examples of these, but you need machines/computers to 'see' them. our human eyes can see less than 1% of the types of light on show.

i hope I'm making sense.

Because they reflect light.

Its like asking how is it possible for someone to send money if they didn't physically make it.

Yellow photons are reflected off of a banana. They travel from the banana to your eye. Therefore the light is from the banana, as far as perception is concerned. The banana is reflecting yellow photons in the presence of light so it is visible and yellow. Dunno how else to say it.

In reality “to see” is the effect of light on our eye. Actually we can not see the light. Rays of different wavelengths create different effects on our eye. In Light Physics a wave is expressed in wavelengths rather than frequency. We would see nothing if rays do not reach to our eye. When an object is exposed to light, it absorbs some of the light and what it does not absorb is reflected back. This reflected light from an object creates an effect in our eye which is “seeing the object”.
