Their lifetime is too short for life to begin or evolve.

Explanation:

A massive star is considered to have at least 8 times the mass of our sun.

A star this big, burns its main-sequence stage much faster than others, as it burns many times more fuel. The scientist community believes that most massive stars have a lifetime of around 2.5 or 3.2 billion years, which would not be enough for life to flourish in a planet orbiting the star.

Plus, massive stars die in the form of supernovae, causing life to be permanently unsustainable on the surrounding planets.
