No. I want to believe.
No one asserted he wrote it at a desk, and those technologies did not exist 65 years ago, much less 3500, but I trust you know that
But any technology would have been available to God at any time. I find it absurd that God would only directly communicate to people thousands of years ago, but not today.
There is no a longer a need to, as the scripture says:
Hebrews 1:1 In the past God spoke to our ancestors through the prophets at many times and in various ways,
2 but in these last days he has spoken to us by his Son, whom he appointed heir of all things, and through whom also he made the universe.
The purpose for the scriptures was so that we may be wise unto salvation, which is only through Jesus Christ. However, if a person can be deceived into doubting any one thing in the Bible as authoritative (e.g. creation week), then that person is liable to be deceived as to the identity, mission and Deity of Jesus Christ, who created the universe! There is no more need for new scripture today, for Jesus, whom the prophets foretold and who was foreshadowed in the Law, is the Reality!
John 20:30 Jesus performed many other signs in the presence of his disciples, which are not recorded in this book.
31 But these are written that you may believe that Jesus is the Messiah, the Son of God, and that by believing you may have life in his name.
We have been given ultimate evidence, in these last days, to the wisdom and knowledge of God: DNA. It self replicate, corrects, and wraps itself into a tiny package, and is in everyone of our cells! It is the most complex data recording mechanism known to man, so incredibly complex and dense that all of the worlds data could fit in a teaspoon of it! (source: here)
Yet, so called scientists dismiss this complexity with explanations of evolution and long periods of time.
Ephesians 4:18 They are darkened in their understanding and separated from the life of God because of the ignorance that is in them due to the hardening of their hearts.
See: Psalm 104:2, Isaiah 40:22 & 44:24, Zechariah 12:1, Job 9:8 & 26:7, and Jeremiah 10:12.
