They can be explained rationally but let me tell you a question(as you advised me before to do some teaching in my comments, so please concentrate on learning more than trying to think of an answer to it, it's your advice anyway buddy.
you do see what such thinking does, you keep arguing, and it always ends up with you asking for proof, well, these guys' wish was granted, and see what they keep doing
91. Surat Ash-Shams, Meccan, 15 verses
(11) The Thamud (people) rejected (their prophet) through their inordinate wrong-doing, (12) Behold, the most wicked man among them was deputed (for impiety). (13) But the Messenger of Allah said to them: "It is a She-camel of Allah. And (bar her not from) having her drink!" (14) Then they rejected him (as a false prophet), and they hamstrung her. So their Lord, on account of their crime, obliterated their traces and made them equal (in destruction, high and low)!
54. Surat Al-Qamar, Meccan, 55 verses
(23) The Thamud (also) rejected (their) Warners. (24) For they said: "What! a man! a Solitary one from among ourselves! shall we follow such a one? Truly should we then be straying in mind, and mad! (25) "Is it that the Message is sent to him, of all people amongst us? Nay, he is a liar, an insolent one!" (26) Ah! they will know on the morrow, which is the liar, the insolent one! (27) For We will send the she-camel by way of trial for them. So watch them, (O Salih), and possess thyself in patience! (28) And tell them that the water is to be divided between them: Each one's right to drink being brought forward (by suitable turns). (29) But they called to their companion, and he took a sword in hand, and hamstrung (her).
7. Surat Al-A'raf, Meccan, 206 verses( I really recommend you read the whole thing, it really answers most of the questions raised here, just try to be objective and think out side the box)
(73) To the Thamud people (We sent) Salih, one of their own brethren: He said: "O my people! worship Allah. ye have no other god but Him. Now hath come unto you a clear (Sign) from your Lord! This she-camel of Allah is a Sign unto you: So leave her to graze in Allah's earth, and let her come to no harm, or ye shall be seized with a grievous punishment. (74) "And remember how He made you inheritors after the 'Ad people and gave you habitations in the land: ye build for yourselves palaces and castles in (open) plains, and care out homes in the mountains; so bring to remembrance the benefits (ye have received) from Allah, and refrain from evil and mischief on the earth." (75) The leaders of the arrogant party among his people said to those who were reckoned powerless - those among them who believed: "know ye indeed that Salih is an apostle from his Lord?" They said: "We do indeed believe in the revelation which hath been sent through him." (76) The Arrogant party said: "For our part, we reject what ye believe in." (77) Then they ham-strung the she-camel, and insolently defied the order of their Lord, saying: "O Salih! bring about thy threats, if thou art an apostle (of Allah.!"
