May I ask what if someone is going to try to question for every objects as well as other subjects such as this thread, which is continuous and also ridiculous yet contentable to him somehow as like as if this is a cotton candy in his hand which he paid about $5 for it when he realized that he was in the amusement park called Dream with his girlfriend whose existence had been proven neither by any researches nor experiment, in order to prove that he is proving his own existence based on the quote from Rene Descartes through his action of thinking about himself as a questioning guy for the reason of the presence of this thread?
