“every fixed star has its planets, and every planet its own creatures”

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.
