Are scientific findings a test to Christians' Faith?

I take the general approach that, "The honest pursuit of truth will always lead you to God". We are living in the creation of God, after all. The problem is, we are not smart enough to understand and interpret what we find, and we fill in the blanks with our own agenda. Old earth, young earth, or somewhere in between... I don't know, but as our understanding of HONEST science increases, I believe it will undoubtedly point to the God we have faith in. I do not believe that science as a rule should be disregarded whenever it challenges our faith.

In the meantime, this is a hard question to answer and not offend someone's belief. I have a scientific mind, and tend to think that our Earth is probably older than the "young" earth theory holds. I don't believe we have all the evidence to conclude one way or the other. Perhaps the nature of time has changed since the creation; things were happening very fast in the beginning, and it's plausible that a human perception/understanding of time has changed. Perhaps there are nuances in the language in the Old Testament regarding figurative or concrete interpretations that may have some relevance.

I do know that God is not afraid of our questions, and it is not a sign of weak faith to ask God for answers. You may even argue that asking God for answers is a sign of strong faith. It could possibly be there are answers and hints in the world He created.

That's a good question but one you already know the answer to.

The LORD then answered Job and said: Will one who argues with the Almighty be corrected?

Job 40 (NABRE)

There is no sense arguing with God and His Creation.

Then the LORD answered Job out of the storm and said: Gird up your loins now, like a man. I will question you, and you tell me the answers! Would you refuse to acknowledge my right? Would you condemn me that you may be justified?

Furthermore man has no right or justification for questioning God's creation.

Let creation be a mystery and leave it at that, it should still be compatible with your faith to say to say, "I don't fully understand the biblical account of creation".

Scientists plumbing the depths of what it is possible to know seem to be consistently finding that there is more stuff that they didn't even know that it was possible to know even while they prove that they now know things they previously said were impossible to know in the first place.

One should be mindful of 1 Thessalonians 5:20-21 (ESV):

²⁰Do not despise prophecies, ²¹but test everything; hold fast what is good.

and of Proverbs 14:15 (ESV):

The simple believes everything, but the prudent gives thought to his steps.

and of Proverbs 4:5-7 (ESV):

⁵Get wisdom; get insight; do not forget, and do not turn away from the words of my mouth. ⁶Do not forsake her, and she will keep you; love her, and she will guard you. ⁷ The beginning of wisdom is this: Get wisdom, and whatever you get, get insight.

These provides some support for the idea that faith is not meant to replace evidence or common sense entirely. Thus, if you read Deuteronomy 14:7, ESV:

Yet of those that chew the cud or have the hoof cloven you shall not eat these: the camel, the hare, and the rock badger, because they chew the cud but do not part the hoof, are unclean for you.

and you go find that hares neither chew cud nor do they have cloven hooves, you don't assert that hares do actually chew cud but don't when anyone is looking in order to test us, but instead decide that you were perhaps interpreting the passage wrong; maybe "chew cud" was intended just to mean "eat grass", or was a more poetic way of getting the point across: don't eat hares, even if you think they fall under the earlier rule of allowed animals.

So do not be too sure that the test, if there is one, is to believe one interpretation of, say, Genesis 1, in the face of massive, overwhelming evidence. Maybe instead the test, to the extent that there is one, is to pay attention to the overwhelming evidence and think more deeply about why Genesis 1 is written the way it is.
