I see nothing of the sort "in me" that "testifies to a maker". This is just dogma based upon a religious belief. And tell me which one, and in which holy book, you get this idea from??? I doubt you can claim an extra-biblical source here. All you have done is offered opinion, if you are not including your biblical foundation.
But on the purely naturalistic level, men DO have the ability to know what is right, relative to the culture they live. However, in the United States, much of that culture WAS [and still is] highly affected by a religious undertone. And that religious undertone has been influenced by the religious text, the bible. So we're back to square one . . . . . and why I jumped to the conclusion that you are expecting people to follow biblical law.
Yes, there are certain aspects of humanity that we have been made to [probably written in our DNA, I don't know] see as "wrong". Let's take the traditionally held "10 commandments", for example. Let's see if these are "engraved on my conscience". And for "my conscience", I will qualify that with "that which I agree with".
10 - “You shall not covet your neighbor's house; you shall not covet your neighbor's wife, nor his male servant, nor his female servant, nor his ox, nor his donkey, nor anything that is your neighbor's.”
There is nothing immoral in wishing you had what your neighbor does. Only if you steal it. What it CAN do is motivate you to better yourself. Is that one "engraved in my conscience"? No.
As a side note, there is a part of that commandment that should make a person question. I'll let you figure out which part.
9 - “You shall not bear false witness against your neighbor."
You shouldn't lie about people. "Engraved on my conscience"? Perhaps so.
8 - “You shall not steal." If it belongs to another person, you would violate their personal rights. "Engraved on my conscience"? I would say, yes.
7 - “You shall not commit adultery."
Having relations with someone who isn't your spouse can result in problems and inner pain. I can choose, whether "right or wrong", not to, for my own sake. "Engraved on my conscience"? Sure, but it is more about wronging another person [the spouse of the one you are having relations with].
6 - “You shall not murder."
Without a VERY good reason [war, person protection], murder is unethical. "Engraved on my conscience"? Yes, it is.
5 - “Honor your father and your mother, that your days may be long upon the land...".
Though honoring your parents has nothing to do with how long you live, it is a very good thing to do. . . . . unless the parents are abusive. So relatively, "Engraved on
MY consience"? Because of who my parents are, . . . ABSOLUTELY.
4 - “Remember the Sabbath day, to keep it holy. Six days you shall labor and do all your work, but the seventh day is the Sabbath of the Lord your God."
I labor for 5 days. . . as does many. "Engraved on my conscience"? Hardly. Which ever day "the sabbath" is on, . . . it's just another day.
3 - “You shall not take the name of the Lord your God in vain, for the Lord will not hold him guiltless who takes His name in vain."
What "name" is that? I don't use any such terminology in my speech. "Engraved on my conscience"? Not at all.
2 - “You shall not make for yourself a carved image, or any likeness of anything that is in heaven above, or that is in the earth beneath, or that is in the water under the earth; you shall not bow down to them nor serve them. For I, the Lord your God, am a jealous God, visiting the iniquity of the fathers on the children to the third and fourth generations of those who hate Me, but showing mercy to thousands, to those who love Me and keep My Commandments."
There is a lot in this one that could be touched on, but for another thread. "Engraved on my conscience?" Not at all.
1 - “I am the Lord your God, who brought you out of the land of Egypt, out of the house of bondage. You shall have no other gods before Me.
Firstly, . . . . I haven't ever been to Egypt.
This thread is all about "evidence for this god mentioned in the christian bible". It is the crux of the issue. There is no more evidence for this god than any other god that has been worshipped by MANY cultures in the world. Until that can be established, . . . . is this one engraved on my conscience? Absolutely not.
