The oldest ice cores (taken from the Antarctic) date back some 1.5 million years. There are some variables that can introduce error, but it (the error) will be small compared to the age of the recovered materials. This is not theory. Proven laboratory techniques allow us to make these statements. No one who understands the physics of the methods will gainsay them. The physics is not that difficult to get a handle on. But remove any religious (or other) blinders before looking at the science. A link is provided to the white paper on these core samples.
The oldest continental crust would be between three and one half to four billion years older than the oldest oceanic crust. This is due to the fact that ocean plates are subducted under the continental plates, subjected to partial melt and essentially recycled in the mantle before reforming.
The oldest continental crust is significantly older than the oldest oceanic crust. The oldest continental rocks, found in regions like Canada and Australia, are over 4 billion years old. In contrast, the oldest oceanic crust, located at the bottom of the Atlantic Ocean, is only about 200 million years old, as it is continuously created and destroyed through the process of plate tectonics. This stark difference highlights the stability and longevity of continental crust compared to the dynamic nature of oceanic crust.

The oldest continental crust is significantly older than the oldest oceanic crust. The oldest continental rocks, found in regions like Canada and Greenland, date back about 4 billion years, while the oldest oceanic crust is around 200 million years old. This age difference is primarily due to the processes of plate tectonics, where continental crust tends to be more stable and less subject to recycling compared to oceanic crust, which is continuously formed and destroyed at mid-ocean ridges and subduction zones.
According to ocean drilling data, the oldest oceanic crust is found in the eastern Mediterranean Sea, particularly in the vicinity of the island of Cyprus, with some sections dating back to around 200 million years ago. This crust is significantly younger than continental crust, which can be billions of years old. The age of oceanic crust generally increases as one moves away from mid-ocean ridges, where new crust is formed.

The oldest oceanic crust is in the west Pacific and north-west Atlantic. They are about 180 to 200 million years old.

The oldest rocks are actually on land but in the ocean crust they would be the rocks closest to land. The mid-ocean ridge forms new rocks. They are usually located in the middle of the ocean.
The oldest rock in oceanic crust is that which is found the greatest distance from a mid-ocean-ridge.
