In the same lifetime does not count? Are you aware that Greek states formed policies based on these oracles?
Example 1:
Athens sends to Delphi for an oracle seeking for advice on what to do about the coming Persian invasion. The oracle tells them to put their faith in their wooden walls. The Athenian strategists debate what this means. Some side with the interpretation that they should defend their city walls and make a stand on the Acropolis. Themistocles suggests that the wooden walls refers to their navy, Eventually they take this interpretation, and evacuate the whole of the Athenian population to Troizen across the bay, and if need be, elsewhere. Athens, left empty, is burned by the Persians. However, the Athenian strategy, based on their reading of the oracle, makes itself felt, as the military strength of the Greeks and principally the Athenians, transferred to their ships, defeats the Persians in the naval battle of Salamis. Thus we have the oracle, the discussion of the oracle and the formation of policy based on the oracle, and the fulfilment of the oracle.
Is there anything so substantial in the historical concerning the prophecies of the bible? Another oracle from that time resulted in Leonidas leading his 300 Spartans to Thermopylae to make a stand. We know the historicity of that stand because Alexander referred to it when he sent back 300 suits of Persian armour after Granicus, with a note singling out the Spartans for their absence.
Go read some history books. Heck, go read some books that aren't the bible.
