to be honest,no one probably knows.maybe because of their mass
The first stars lacked heavy elements for Earth-like planets. Solar systems form from collapsing clouds of gas and dust.
The first stars to form did not have solar systems with Earth-like planets and satellites due to the lack of heavy elements in their composition. It was only after multiple generations of stars went through nucleosynthesis and produced heavier elements that planets like Earth could form.
Regularities among planets indicate that solar systems form from collapsing clouds of gas and dust, where material coalesces to form stars and planetary systems. Astronomical observations show similar circumstellar disks around other stars, suggesting that all planetary systems likely form in comparable ways.
The first stars lacked heavy elements essential for forming Earth-like planets. These Population III stars eventually exploded as supernovae, enriching the interstellar medium with heavy elements. Later generations of stars, containing these elements, were able to form rocky planets like Earth.
