I disagree for 4 reasons.
Sorry, but I am still not buying the tektites theory for four reasons;
1. They are all roughly the same size. Tektites vary in size.
2. They are all chemically the same. Tektites vary chemically, depending on what parent material the impactor melted.
3. They are all spherical, Tektites come in all shapes- spherical, teardrop, egg shape, etc. The larger they are, the less spherical they usually are.
4. They are evenly distributed throughout the layers. Tektites are usually confined to one layer.
