Remembrance like that is the only 'scientifically observable way' of the closest thing of immortality we can attain.
It even works for fictional entities like jesus, aka rabbi yeshua bar yosef.
You wouldn't even know about the existence of that character without careful repetition of the stories about it.
Without this, you might as well never have existed, soul or no soul.
We do this today despite christianization, we keep our dead in memory even though we could just say "Oh he's in heaven now, with yahweh, and happy" but ...actions speak more than talk.
Europe was never fully christianized, it's a patina over the truth.
It can come back, no worries.
