Not to derail this into a science/religion debate, but this quote misrepresents science. Scientific truth is based on evidence, and the accumulated evidence supports evolution, not intelligent design.
If you believe there's any evidence that supports evolution over creation, you would have to post it, so I can see what it is. The fact of the matter is living organisms do not... nor have they ever behaved in the way Charles Darwin theorized.
There's a pattern, but it is hardly consistent. Wildly changing the definition of 'generation', multiple date changes and other 'new light' reflects an inconsistency that is incompatible with the term 'truth'.
Opposers of Jehovah's Witnesses always dance a gig around the exact same issues: the definition of the generation in Matthew 24:34-35 or speculation about Armageddon. There's no clear explanations for the exact timing of these events in the Bible.
Concerning that day and hour nobody knows, neither the angels of the heavens nor the Son, but only the Father. Matthew 24:36
The faithful and discreet slave while at times mistaken, clearly outline the criteria for the conclusions they reached while conducting diligent research.
Whatever the case, the flaws are there. And in abundance. Which makes them no different than the churches of 'Christendom' they are so eager to criticize.
There were not just mere flaws in Christendom's churches, there was an apostasy that blocked the way to God.

Historian Will Durant explains: “The Church took over some religious customs and forms common in pre-Christian [pagan] Rome—the stole and other vestments of pagan priests, the use of incense and holy water in purifications, the burning of candles and an everlasting light before the altar, the worship of the saints, the architecture of the basilica, the law of Rome as a basis for canon law, the title of Pontifex Maximus for the Supreme Pontiff, and, in the fourth century, the Latin language . . . Soon the bishops, rather than the Roman prefects, would be the source of order and the seat of power in the cities; the metropolitans, or archbishops, would support, if not supplant, the provincial governors; and the synod of bishops would succeed the provincial assembly. The Roman Church followed in the footsteps of the Roman state.”—The Story of Civilization: Part III—Caesar and Christ.
This attitude of compromise with the Roman world stands in stark contrast to the teachings of Christ and the apostles. The apostle Peter counseled: “Beloved ones, . . . I am arousing your clear thinking faculties by way of a reminder, that you should remember the sayings previously spoken by the holy prophets and the commandment of the Lord and Savior through your apostles. You, therefore, beloved ones, having this advance knowledge, be on your guard that you may not be led away with them by the error of the law-defying people and fall from your own steadfastness.” Paul clearly counseled: “Do not become unevenly yoked with unbelievers. For what fellowship do righteousness and lawlessness have? Or what sharing does light have with darkness? . . . ‘“Therefore get out from among them, and separate yourselves,” says Jehovah, “and quit touching the unclean thing”’; ‘“and I will take you in.”’”—2 Peter 3:1, 2, 17; 2 Corinthians 6:14-17; Revelation 18:2-5.
In spite of this clear admonition, apostate Christians of the second century took on the trappings of the pagan Roman religion. They moved away from their pure Biblical origins and instead clothed themselves with pagan Roman garb and titles and became imbued with Greek philosophy. Professor Wolfson of Harvard University explains in The Crucible of Christianity that in the second century, there was a great influx into Christianity of “philosophically trained gentiles.” These admired the wisdom of the Greeks and thought they saw similarities between Greek philosophy and teachings of the Scriptures. Wolfson continues: “Sometimes they variously express themselves to the effect that philosophy is God’s special gift to the Greeks by way of human reason as Scripture is to the Jews by way of direct revelation.” He continues: “The Fathers of the Church . . . entered upon their systematic undertaking to show how, behind the homely language in which Scripture likes to express itself, there are hidden the teachings of the philosophers couched in the obscure technical terms coined in their Academy, Lyceum, and Porch [centers for philosophical discussion].”
