Now back to your question – does Darwinian Evolution contradict Catholicism? YES. Catholicism (just like any Christian belief, including Protestantism), is based on “God creating the heavens and the Earth.” The whole point of Evolution is to deny the existence of God.
Here are some of the MANY problems with Evolution – by definition, Evolution began with one organism, then grew by a tree-like progression into all life. But there is no evidence of a SINGLE TREE – pre-Cambrian strata are void of life, then comes the “Cambrian Explosion” – sudden appearance of MULTIPLE trees, simultaneously. This better reflects a creative event, not slow continuous progression from one point.
But prior to this, that “one point” – all Evolutionists cherish an experiment performed by Stanley Miller (under direction of Harold Urey), in which he filled a flask with water, methane, ethane, amonia, nitrogen, and no free oxygen. Theorizing there was LIGHTNING, he ran a high-voltage arc for several days. He then found AMINO ACIDS in his “primordial soup”, the newspapers proclaiming, “SCIENTISTS CREATE LIFE IN THE LABORATORY!”
Here are several problems:
His flask contained no oxygen, oxygen would poison the solution and prevent amino acids; nowhere in the geological stack do we have evidence of NO FREE OXYGEN.
The amino acids produced were very simple, nowhere near Human base proteins of adenine, cytosine, thymine, and guanine.
The amino acids produced were in EQUAL quantities of right-handed isomers and left-handed; all life uses only left-handed.
The “experiment” was OPEN, it had a circulation system (non-naturally occurring!) An open experiment is not an experiment, it is THEATRICS!
The circulation system had an AMINO ACID TRAP, placed to carefully catch and protect any amino acids; the trap is non-naturally-occurring, and without the trap the destruct rate was BILLIONS to ONE – no amino acids would have been produced!
So the experiment was a complete fraud. But let’s pretend it was legitimate – let’s say we have a pool of “primordial ooze” (soup). Ask any Evolutionists “how did only left-handed molecules pull themselves out of solution, and form themselves into living, replicating life?”
Human DNA exists in 23 chromosome pairs, 46 with sequences of A C T and G of three billion segments each. Three billion, times forty six. But let’s pretend we can have a living organism with only ten units – and we’ll be unimaginably generous and give the probability of simultaneous occurrence of each protein, once chance in a thousand. Therefore for all ten to get together, the probability is 1 times 10 to the thirtieth power.
No way that’s ever going to happen. But they believe it DID — and now understand it happened TWICE in literally the same geological instant, because also formed are “mitochondria”.
Now. DNA does not function without being contained in a CELL, but cellular walls are created by DNA. So how did it start?
Somehow a cell figured out how to create itself, and nearby a mitochondria also solved the “cellular wall hurdle”. Then THIRD thing happened, perhaps a rock fell and GASHED the poor struggling cell, and some mitochondria got inside, and both discovered they could live symbiotically together, better than separate!
Do you begin to see the ABSURDITY? The probability of only a TEN-UNIT chain forming, is zero. The probability of forty six chains, of three billion each, is much, much, MUCH worse. Then it had to happen a second time for mitochondria, then a chance accident to combine them! Evolutionists have NO theory of how it began, no model, nothing – they just BELIEVE. Something that is accepted “on belief”, is a FAITH – it is a pure religion! And it takes BILLIONS and BILLIONS of times more faith to believe in “spontaneous generation”, than to believe an extra-dimensional physicist/engineer/biologist (God!) did it!
So that’s where your Dad is; clinging onto the GREATEST RELIGION of ALL TIME, which does not fit the facts, so that he can reject GOD and the Bible’s account, when God’s Biblical story is sooooo much more credible!
Be very careful discussing this with your Dad; you have to be completely respectful, else you’ll make him mad and close him to the discussion. But these facts are absolute, and the facts themselves can cause anger. Be respectful, kind, and very very patient.
…and we will gladly lift you and him in prayer!
