There is a spiritual koach that Hashem gives to certain Tzaddikim who are basically totally absorbed in Torah and Avodah that they can see or sense certain things that we cannot. There are many stories with the Steipler, the Baba Sali and others zatzal. These stories happened recently enough and they were told over by eye witnesses and the people it happened to. So you basically want to say that all these people are lying and that the brachos and havtachos that various Tzaddikim gave that came true is all made up or coincidence. YOU CALL YOURSELF RATIONAL?!
Yes gedolim are human they aren’t aliens but what makes them great is their determination and success in overcoming their natural human inclinations and limitations and physical drives to become masters of their free will.
