I've been thinking, the bible say nothing about the age of the earth or universe, yet so many christians call it blasphemy if you say that the world is older than 6,000 years, yet the bible itself say nothing at all about the age of the world, also, many christians would call it blasphemy to think that there are other planets that are livable, I admit that, if you do believe the bible than other livable planets wouldn't make much since, I mean, if you believe that the bible is from god, wouldn't god of told the writers of the bible about any other planets? but does the bible say any thing about this planet being the only livable one?
