Not really. Lack of understanding says little, nearly nothing even, about the quality of the data itself.
And even for the most ignorant of us, there are plenty of good reasons to accept the evidence for Evolution. While it is true that much of it is simply way beyond the intelectual background and capabilities of the average person, it is just as true that the indirect evidence is all but impossible for any reasonable person to deny.
One stance of indirect evidence is that it has been used for practical applications and proven reliable every time.
Another is that mutations and speciation are both amply demonstrated, among other examples by the development of nylon-eating bacteria a few years ago.
Then there is simply accademic rivality. It is simply unthinkable that so many researchers worldwide would somehow settle into a deep conspiracy of misdirection when they are hardly united on anything else of comparable complexity, and there are so many thousands of them, nearly all of them vulnerable to some degree or another to the lure of attaining fame and perhaps fortune by presenting quality evidence of a revolutionary finding.
One can also consider the lack of serious challenge to the Theory of Evolution. There has simply been no actual alternate explanation proposed, nothing that could explain observable facts better than the ToE. Nor has there been anything among the many and constant uses and tests of it that even hints that it is flawed or even really incomplete. Sad as it is to say, what passes for challenges to the ToE are actually a sorry mix of misinformation, ignorance, wishful thinking and plain old dishonesty. It is simply not capable of going anywhere near the actual disputation of the validity of Evolution as science, nor as truth. That an anti-Evolution movement exists at all says a lot about the situation of our education, and very little indeed about the situation of the Theory of Evolution.
Ultimately, we have no more reason to hold suspicion about the ToE than about, say, the current understanding that nutrients are mainly carbohydrates, fats and proteins. I can hardly claim to have "witnessed that in person", but I have plenty of indirect yet reliable evidence that it is so at least in the general sense.
Let me present a theory that is much older than your ToE.
"And God said, Let the earth bring forth grass, the herb yielding seed, and the fruit tree yielding fruit
after his kind, whose seed is in itself, upon the earth: and it was so. And the earth brought forth grass, and herb yielding seed
after his kind, and the tree yielding fruit, whose seed was in itself,
after his kind: and God saw that it was good."
(Genesis 1:11-12)
"And God said, Let the waters bring forth abundantly the moving creature that hath life, and fowl that may fly above the earth in the open firmament of heaven. And God created great whales, and every living creature that moveth, which the waters brought forth abundantly,
after their kind, and every winged fowl
after his kind: and God saw that it was good."
(Genesis 1:20-21)
Do you not notice that the birds were brought forth from "the waters" of the earth? How do you suppose that happened? Could it be that God is hinting at evolution?
Did you see what it said? It said, "
Let the waters bring forth"
Who brought forth? The waters brought forth.
Why? Because God declared it to them.
"And God said,
Let the earth bring forth the living creature
after his kind, cattle, and creeping thing, and beast
of the earth after his kind: and it was so. And God made the beast
of the earth after his kind, and cattle
after their kind, and every thing that creepeth upon the earth
after his kind"
(Genesis 1:24-25)
Let the earth bring forth, God commanded.
Each living creature being created "after his kind".
The idea that a species can evolve into a new creature, is by no means a modern concept. It's been around for thousands of years. Even cavemen and goat herders hinted at such things.
