Do aliens exists in this world is anything mentioned in the bible in relation to this topic?

Answer by Richard Geraghty on 07-08-2013:

Dear Vidya,

Whether Aliens from out space exist or not is a side question who's answer does not tell us anything new. The truth we know for sure is that God in the person of Christ died to save the sons and daughters of Adam and Eve from there sins. This is a truth which will always be true.
