This question already has an answer here:
Islam clearly mentions how life(humans/animals) was formed in Quran:
And Allah has Created every animal from water; of them are some creeping on their bellies; some walk on two legs; and some on four. Allah Creates what He wills: for sure Allah has Power over all things. [Noble Quran 24:45]
while the stages of creation of Life were also defined in Quran:
وَقَدْ خَلَقَكُمْ أَطْوَارًا
While He(Allah) has created you in stages. Quran(71:14).
I am curious to know, if Islam specifically accepts or denies the existence of life beyond earth.
