Scholars traveling through the Middle East traveled with caravans, therefore during his early life before he "recited" (starting when he was about 40) the Qur'an, he would have been exposed to Judaism, Coptic and Eastern Christianity, and scholars who understood Greek science. We are not addressing a "few seconds", we are addressing decades of exposure to conversations with men while traveling, at rest stops, and at merchants where he bought and sold his merchandise.
You say that God revealed truths to Muhammad, and I have shown you that at least one of your "truths" is not true, and that Muhammad could have easily learned about the "stretching" or "expanding" of the universe from sources other than God since this is recorded in more than one Scripture.
The Qur'an disagrees and contradicts the Bible, which you have admitted you cannot prove was changed by either Jews or Christians. Allah claims authorship of the Bible, where we as Christians are told "to love our enemies" and "not take our own revenge" while Allah told Muhammad to "kill unbelievers where you find them". God tells Christians that church leaders should "be husbands of one wife" and Muhammad had 19 wives and teaches Muslims they can have up to 4 wives.
In the Bible God tells us that He does have a Son, and Allah says he does not have a son. In the Bible we are told Mary had 6 children other than Jesus and the Qur'an disagree. The Qur'an says Jesus made clay birds, and an apocryphal book that is rejected as truth records that Jesus not only made clay birds but gave those birds life.
Allah told Muhammad that Israel belongs to the Jews, and modern Muslims tell the Jews they have not right to that sliver of land.
We have more than 26000 manuscripts and parts of manuscripts to support the accuracy of the Bible and Islam has zilch to support the accuracy or authenticity of the Qur'an.
You want to appeal to science, well I can appeal to the science of manuscript evidence to show the Bible has been preserved by God for over 4000 years.
What do you have to offer? A religion that used fear, extortion, the sword, and lies since the 8th century.
