In one of the videos I thought it said the planet was uninhabitable but then it said there were these "aliens". Who knows? But I do think it is possible that something like this could be on the way and the government doesn't want us to know so as not to panic. I think they keep a lot of things from us. If something like this is about to happen there is nothing that can be done except trust the Lord to take care of His people.
Very wise words! And I totally agree...
I'm not scared of this anymore. God is in control and I am now at peace with 12.21.2012, IF that ever happens.
