Geophysicist Presents 50 Glacial Cycles as Evidence Against Young Earth Timeline

What was said

"This is a 5-kilometer sediment core. What does this sediment core show? It shows about 50 cycles. In each cycle, there's about 100 meters of sediment that oscillates between rising sea levels, high-stand sea levels, then falling sea levels. This cannot be explained using a flood narrative."

PhD Tony presented evidence from a five-kilometer sediment core from Wanganui, New Zealand showing 50 distinct glacial cycles with corresponding sea level changes. He argued these repeated patterns, confirmed by oxygen isotope data, cannot be explained by young earth creationism or Noah's Flood and demonstrate millions of years of geological history.
