how to refute the claim that the signs are no longer what they were?

[loki88]

Many claim that the signs as they were known in eg. chaldea or Egypt are no longer in the same position in the sky thereby nullifying the validity of astrology as a science. Anyone care to refute this?

Learn astrology yourself and tell them intricate details about their personality just by knowing their birth data. Then ask them again if they think it's invalid lol.
