Yes, there was a specific day, or even a thousand-year “age” if you want to run with that meaning of “yom,” in which Adam was created.
There are six of these Creation days or “yom” in series, though, and you ignore that, in order to interpret Biblical Creation as only dealing with mankind, only on Earth.
It’s also problematic to espouse the possible, thousand-year meaning of “yom” in an attempt at making wiggle room for evolution. Stretch out the six days of Creation, and one day of rest, under any accepted meaning of “yom,” and you have, at most, 6,000 years, plus 1,000 years of rest.
It doesn’t work, Radix. God is not going to lie to us, allegorically or literally, and that would make the Genesis account a lie, either way.
