Why most human beings turn away in disbelief?

Moses and Jesus and Mohammad ( peace be upon them all ) had power from God to Challenge the blasphemers

Moses time where the magic was the most popular so God gave Moses the stick and with it he open the red sea and walk thru with his people.

Moses said, "Certainly not. My Lord is with me and He will certainly guide me." (63) We sent a revelation to Moses saying, "Strike the sea with your staff." The sea was rent asunder and each side stood high up like a huge mountain. (64) Then We brought the two parties closer. (65) We saved Moses and all the people with him (66) and drowned the other party. (67) In this there was certainly evidence (of the Truth), but most of them did not have any faith. (68) Your Lord is certainly Majestic and All-merciful. (69)

Jesus time where the medical and medicine is the most popular so God made him the best doctor knowledged so he did the following

When God said, "Jesus, son of Mary, recall My favors to you and your mother. (Recall) how I supported you by the holy spirit, made you speak to people from your cradle and when you grew up, taught you the Book, gave you wisdom, the Torah, and the Gospel. (Recall) when, by My will, you made a sculpture of a bird out of clay, blew into it, and it turned into a real bird by My Will. (Recall) how, by My will, you healed the deaf, the lepers, and raised the dead. (Recall) when you came to the Israelites in the house with clear miracles and I saved you from their mischief, even though the disbelievers among them said, "This is obviously magic". (110) (Recall) when I inspired the disciples to have faith in Me and My Messenger. They said, "We have accepted the faith. Lord, bear witness that we have submitted ourselves to Your will" (111) (Recall) when the disciples said, "Jesus, son of Mary, can your Lord send us a table full of food from heaven?" and you replied, "Have fear of God if you are true believers". (112) They said, "We only wish to eat therefrom to comfort our hearts, to know that you have spoken the Truth to us, and to bear witness to it along with the others." (113)

Mohammad time where the poetry is the most popular at that time so God reveled to him the Quran which no mankind can do one page thou Mohammad was illiterate person,

Alif. Lam. Mim. (1) There is no doubt that this book is a guide for the pious; (2) the pious who believe in the unseen, attend to prayer, give in charity part of what We have granted them; (3) who have faith in what has been revealed to you and others before you and have strong faith in the life hereafter. (4) It is the pious who follow the guidance of their Lord and gain lasting happiness. (5)

(87) Say, "If all human beings and jinn were to come together to bring the equivalent of this Quran, they could not do so, even if they all were to help each other. (88) We have mentioned in this Quran all kinds of examples for the human being, but most human beings turn away in disbelief
