It is intuitively obvious to the believer that Darwin, Freud, Marx and
Heigel  were written to undermine the Christian foundations of
civilization.  Their intent in teaching the man is only an animal was
to give excuse for the hedonistic lifestyle prevalent to the upper
classes of the Victorian age.  A generation that did an outward show
of  civilization, but privately indulged in every imaginable  form of
lust, greed and evil...
But about Darwin.

Modern paganism    https://creation.com/evolution-ancient-pagan-idea

a quote:

More recently, scientists have been thinking up ‘new’ theories to
explain how life could have developed on Earth, given the vanishingly
small probability of spontaneous evolution actually happening. The
late Francis Crick, the co-discoverer of DNA’s structure (along with
James Watson and Maurice Wilkins), came to believe that aliens, and
not God, were responsible for life on earth.14 The pagan gods have
struck back with a vengeance!

More recently, much speculation has been made about the ‘multiverse’,
or ‘parallel Universe’ theory, such as a recent article in Scientific
American by Max Tegmark.15,16 This fantasy is quite useful, because
anything can now happen, as in the science fiction Matrix movies!
However, such an idea is ancient. Augustine complained about it before
AD430 when he said:

‘There are some, again, who, though they do not suppose that this
world is eternal, are of opinion either that this is not the only
world, but that there are numberless worlds or that indeed it is the
only one, but that it dies, and is born again at fixed intervals, and
this times without number.’17

‘There is nothing new under the sun.’—King Solomon, Ecclesiastes 1:9-11

Solomon wrote about 3,000 years ago: ‘There is nothing new under the
sun. Is there anything of which it may be said, “See, this is new”? It
has already been in ancient times before us. There is no remembrance
of former things, nor will there be any remembrance of things that are
to come by those who will come after’ (Ecclesiastes 1:9-11).
