I can CONSIDER it all day long. What I can't do is BELIEVE IN IT without evidence! What's so hard to understand here?
One is not doing this. One is asking for evidence to substantiate claims before one believes in them. As most people do in their everyday lives.
If you say to me, "Look outside... there's a bird!"
I believe you. I don't need to look.
If you say to me, "Look outside... there's a dinosaur!"
I don't believe you. I'm going to ask several followup questions unless I happen to be right next to a window. If there's a window, I will look out but will not BELIEVE it's a dinosaur until I see the T-Rex (or whatever) in the parking lot.
I think and I've tried to say this before, its the way you use the word believe that is causing the disagreement. If you had evidence of something you wouldn't believe in it you would know of it. Belief is something people do in absense of evidence. Like how could you possibly have done a thread calculating that 3 million intelligent alien races, all capable of intergalatic space travel, exist in the universe if you didn't believe that aliens exist somewhere in the Universe? People don't calculate the existance of things they don't believe in.
