Well, I doubt this topic was set up intending for a debate. Read the topic. (Though I think a debate on this topic is still within topic)
Also, I was never a 'debate' kind of person, so if you were wishing for a better one, I am so sorry to have disappointed you.
What I have been saying is why I believe that they exist, and my own experiences which lead me to believe.
I have been reiterating that you can choose not to believe if you don't want to.
You don't have to make everyone take your stand and agree with you.
But as for me, I think that there's nothing really impossible in this world. What may seem impossible now may not be in future. There may not be evidences now doesn't mean that there won't be in future. I don't think that idea is impossible. So I am going to believe they exist.
