"Creationism" has several meanings.
There are those who espouse a young earth (perhaps 6000 years old) that was created by God in six, twenty-four hour days. IMHO, that position requires that we ignore the scientific data that clearly refutes such a view.
However, while the evidence of some level of evolution my be "everywhere" it is not sufficient to refute the statement that, "In the beginning, God created the heavens and the earth."
Everything that exists owes it's existence to a prior cause. It could be posited that the universe is infinitely old and that there was never a "time" when it did not exist but, by scientific observation, we know that proposition is false and that our universe is only about 13.7 billion years old. (Though , at the time that evolutionary theory was in its infancy, it was the accepted "science" that the universe was infinitely old and in a static state. The observations of Hubble at the Mt. Wilson observatory proved that "science" to be incorrect.)
The fact that our universe had a beginning requires that there be a cause for that beginning, a "first cause." Those who hold to the truth of a creation, in whatever form, call that first cause "God." So I do firmly believe that it was God Who created the heavens and the earth some 13.7 billion years ago when He spoke to what was yet "formless and void" (singularity???) and said, "Let there be light." That statement was followed by a very "big bang" from which light soon radiated. (Works for me.)
The source of information for Christian creationism is the Bible. But the Bible is not a science book. The account of the creation in Genesis 1 is the beginning of "The Story of Us" for Israel. It is the revelation of God and His desire for an intimate relationship with all mankind. Scripture refers to God as the "husband" of Israel and to the Church as the "bride" of Christ. Those are not scientific terms; those are terms expressing an intimate union.
So, when someone says that the Bible is "not scientific," my response is "So what?" Neither is the Iliad and the Oddyssy. They are literature as are the Baghavad Ghita and the Adventures of Huckleberry Finn. They are not intended to be science textbooks.
The Bible is the revelation of God to mankind. Trying to make it into a science book or criticizing it for its lack of experimentally provable data are both endeavors in absurdity, IMHO.

Ah yes......"first cause".. St. Thomas Aquinas , tho it was the Greeks who probably had already had the original idea.
I love the greeks.....such thinkers, and such warriors....... take the Spartans for example.
Go Leonidas I and the Battle of Thermopylae
First cause is interesting, as truly everything that exists, has a creator., and thus, everything has a beginning, a time-point moment of being created.
It is interesting to note that God created all things, "in time", that is to say, within the boundary of time, yet He exists outside of time and that is why He cant be explained as having a beginning or an end.
Also, God has the distinction of being the original "first cause" Creator and from there, all living things He created make copies., yet God alone created each thing, fully formed, "after its kind" and not as a copy.
Humans are created in the image of God, yet they only know how to recreate.
God creates a living shoreline full of flowers, and man paints it, recreates it, as a landscape, or he builds a nice flower garden using the preexisting.
God creates man out of dirt, out of a rib, and inside a virgin without intercourse or an IVF, and all man can do is combine his sperm with her egg and recreate.
Science, which would attempt to overthrow God with science, has a problem, and this problem they face is that to be a God, you have to be able to create a brand new thing from NOTHING.
Science has a bit of difficulty doing this, as they can take what preexists and manipulate it and come up with something different, and then combine it, or make a hybrid., but they cant create anything at all unless they have some pre-existing material to use.
However, God created everything He created from "scratch".
For example, take something like a Rose......a red Rose.
Science cant create one from "thin air".......they can recreate one from a seed, or take a graft and recreate, or they even clone one , but that is all manipulating the pre-existing......as they cant create a red rose from "thin air"....as only a very creative GOD who is omnipotent can do this, and when He does it, its not a laboratory trick, its an >original creation<.
He did the same regarding the universe.
