Space do not scatter light then how will the suns light reach earth??

There is light in space. Putting aside the wavelengths humans cannot see and focusing only on the visible spectrum, remember that we only see things because light bounces off and reaches our eyes. Certain things absorb certain wavelengths of light and reflect the rest, which is why certain things are certain colors.
If you’re asking why space appears mostly dark, it’s because space is mostly empty. There’s relatively little to emit or reflect light. Earth’s atmosphere distorts and almost “conducts” light; the sun lights up the entire sky during the daytime. Remember, though, that the sun appears to change colors during a sunset: even that relatively small difference in distance between noon and dusk is enough to distort enough light to appear a different color. With enough atmosphere, the sunlight would theoretically be blocked entirely.
However, there is no atmosphere in space, which means that while light can continue unimpeded for incredibly distances, it also isn’t being “conducted” into anything.
Light is present. Almost nothing else is.

Well, light is actually an electromagnetic wave and also it is a non-mechanical wave that is it does not require a medium for it's propogation.
That is in this case to reach from sun to the earth.
However, your question tells that you're confused between two very different concepts.
Scattering of light and propogation of light are two very different but interesting topics in Modern physics.
Now, scattering is actually the separation of different monochromatic light waves from a mixed source due to particular refraction
So, actually the scattering part is connected to the question answering the blue colour of our sky. But light does not require a medium to travel thus it can travel infinite distances and obviously here reach from the sun to the earth.
