As you rightly state, Bahá'u'll'áh affirms that every fixed
star has its planets, and every planet its own creatures. The House of Justice
states however, that it has not discovered anything in the Bahá'í Writings
which would indicate the degree of progress such creatures may have attained.
Obviously, as creatures of earth have managed to construct space probes and send
them into outer space, it can be believed that creatures on other planets may
have succeeded in doing likewise.
