Why can't Planet Mercury and Venus have moons? Is it because they are too near to the Sun?

They can; they just don't.
Clearly Mercury IS big enough to hold a satellite; it's the same size as Pluto. Venus is substantially larger.

Just because they don't have one doesn't mean that the can't. Don't listen to the people who say their gravity isn't strong enough because Pluto has three moons and its gravity is far less than Venus or mercury. This site has some info about Pluto's moons.

They could have moons. They just don't happen to.

there gravity is so small that it can't attract a moon into their orbit.
