Short Answer

Real logic does not mix in rationalized speculations and fairytales.  The Secular religion doesn’t use real logic. Nor does the Agnostic religion or the Atheist religion. Nor do any other denominations of Secularism. Repeatable experiments and actual observation and pure mathematical logic show us that evolutionism is impossible. Repeatable experiments and actual observation and pure mathematical logic show us that almighty God exists and the He created the universe. They show us that there was a world-wide flood. They show us that the Bible is free from errors. This is all a very big problem for Secular Humanists, Agnostics, and Atheists. Evolution, by the way, isn't science and those who believe in it do so by violating all the rules of logic.

Detailed Answer

The Secular Humanist religion states, as a matter of worldly faith that the human mind is god-like if it is not god. It states that the human mind can make up knowledge. Well, then it has had to go on to state by the same worldly faith that every person's reality is different from every other person's reality. Logic is supposed to use real information to come up with answers. It is mathematical, and the rules of real logic are based on observation. For instance, by observation we know that something cannot be true at the same time that it is false.

Pure thought is not based on logic, however. Logic has limits, and it is always dealing with a limited amount of information. Filling in the blanks with assumptions is not valid. If you change the assumptions, you change the answer. And there is no such thing as a valid assumption.

Many people, today, don't even know whether they are dealing with logic and observation or whether they have crossed over into speculation. Rational-lie-zed speculation is everywhere present. It is the reason that innocent people are sent to prison. It is the reasoning by which Christians argue. It is the basis of most of politics. It is the basis of evolution.

Logic is simply a set of rules that have been observed to be in operation in the world around us. They are the part of the order of the universe that we have been able to observe up until this point. The reality is that logic is not valid if we inject Rational-lie-zed speculations into it. At that point, we are using logic to yield answers that are not realistic. For this reason, logic is very limited. It is valuable, but extending it beyond its limits is merely a method of deception.

Pure thought is based on logic, so the story goes.
We swallow this line easily, as everybody knows.
But reasoning and logic fall short to tell what's true.
And scholars argue constantly all mired in a goo
Of logical assumptions--they all sit in their stew,
As they have done for ages. This is nothing new.

Their books and papers, proven false by that which they can see,
But, proud and haughty, they deny that it can ever be.
Scientist or theologian--they are all the same.
Facts based on assumptions, all stirring in their brains.
A brain so proud, it says to God, "Who are You to tell."
And gives us quite a clue to just how Satan fell.

The more they learn, the more they know, the more confused they are,
For when they learn what isn't true, they're stuck in pitch-black tar.
They look into the Bible, but they don't see the Word.
A veil is there before their eyes. They see what they had heard.
Is God able to reveal? Can His Spirit show--
If we're willing now to yield--things that we must know?

As God reveals, won't He know to show us all the same?
Won't He show us in the way the Bible does proclaim?
For God does send, the Bible says, and tells us how He sends.
He chooses whom He will to send. On that we can depend.
If there is great discord and all this argument,
It simply means that someone runs whom God has never sent.

Reality has a problem with logic in that, if you plug in the wrong values into the formula, you get the wrong answers. If you plug real values into an unproven formula, you also are simply deceiving. There are many other ways that logic is misused to make a case for just about anything including:

global warming
evolution
killing people
the “danger” of the hole in the ozone layer
socialism
communism
anti-Christian attitudes
immorality
anti-family attitudes
hate toward Christians

Since we only know in part, we can't get conclusive answers to many questions using purely mathematical logic. So, logic and observation can do some things, such as build millions of gasoline engines that actually run or make computer chips that work in computers. It is just limited because of incomplete and bad information, plus an incomplete understanding of logic. There is much that we don't know.

Numbers 15:39 . . . and that ye seek not after your own heart and your own eyes, after which ye use to go a whoring:

Psalm 53:1 The fool hath said in his heart, There is no God.

Jeremiah 17:9 The heart is deceitful above all things, and desperately wicked: who can know it?

1 Corinthians 2:14 But the natural man does not receive the things of the Spirit of God: for they are foolishness unto him: neither can he know them, because they are spiritually discerned.

Proverbs 28:26 He that trusteth in his own heart is a fool: but whoso walks wisely, he shall be delivered.

Jeremiah 23:16 Thus says the LORD of hosts, Hearken not unto the words of the prophets that prophesy unto you: they make you vain: they speak a vision of their own heart, and not out of the mouth of the LORD. They say still unto them that despise me, The LORD hath said, Ye shall have peace; and they say unto every one that walks after the imagination of his own heart, No evil shall come upon you.

James 1:17 Every good gift and every perfect gift is from above, and cometh down from the Father of lights, with whom is no variableness, neither shadow of turning.

Summary

The Secular Humanist religion has a problem with logic in that pure repeatable experiments and observation and pure mathematical logic prove that evolutionism is impossible. Pure repeatable experiments and observation and pure mathematical logic prove that God exists and that He created the universe. They prove the world-wide flood. This is all a very big problem for Secular Humanists.  Evolution isn't science.
