Ok, you can make that hypothesis. Now back it up with evidence besides fairy tales in the bible. Otherwise your are as usual as full of shyte as a christmas turkey.
"Although it was discovered that some rocks would reverse their magnetic field while cooling, it became apparent that most magnetized volcanic rocks preserved traces of the Earth's magnetic field at the time the rocks had cooled."

As stated, it is known that sudden cooling of volcanic rock can result in the reversial of the magnetic field. This sudden cooling happened at the time of the flood, not 750,000 years ago.
If the earth were even 20,000 years old, its magnetic field would have been so strong as to make life impossible, based on the present rate of decay. The theories of Humphreys and Lamb can be used to determine how much the magnetic field of an astronomical object should decay after 6,000 years at the present decay rate. The numbers that resulted from Humphreys’s theory not only matched the strengths of the known magnetic fields at the time but also successfully anticipated Voyager 2’s measurements of the magnetic field of Uranus (in 1986) and Neptune (in 1990). These results not only confirmed a creationist theory but also helped confirm that the solar system really is as young as the Bible claims.
In the early 1980s, physicist John Baumgardner developed a creationist theory for the rapid motion of the earth’s crust during the Flood. His theory suggested that the “cold” crust, located beneath the pre-Flood oceans, should have sunk the full 1,800 miles (2900 km) to the base of the earth’s hot mantle, where the temperatures are up to 7,232°F (4000°C). This crust would have melted if it had millions of years to reach the base of the mantle, sinking as slowly as today’s rates. On the other hand, if it sank quickly 4,350 years ago, as Baumgardner’s theory suggested, then piles of those plates should still be found at the base of the mantle, cooler than the mantle around them.
It took ten more years before scientists developed the technology capable of “seeing” something like that at the base of the mantle. When that technology was developed, the cold material was discovered, just as Baumgardner’s model had expected. This successful prediction suggests that Baumgardner’s model is true. It also suggests that continents moved rapidly during the Flood and that the Flood occurred only thousands of years ago,
