It's at least heavily implied in many. It implies that he created everything and all living things on it only talks about creatures being created on earth. If the book is accurate (it's clearly not, but let's assume) and if it's divinely inspired, it should be aware of cresting life elsewhere also. It also calls stars/glalaxies/nebulas/whatever "lights in the dome of the sky" so not exactly a great start for it.

It being weird or wrong hasn't stopped it really before though, but it would probably create some kind of shift, especially if it's intelligent. In that case, are they deserving the same status as man? Are they children of God also? Why do they look different?
