'Sorry, Harry. You quote ONE scientist and his study.'

I could quote many. There are plenty out there if you were interested in looking at both side of the question. I assume therefore that you are not familiar with Sanford's thesis.
That same sex acts are forbidden is not based on whether homosexuality is chosen or not, but that same sex acts represent a fall from the originally perfect state of the complementary union of a man and a woman, and that same sex practices are unhealthy. The answer is celibacy as it used to be for carriers of haemophilia; another of the many defects that flesh is heir to. The suggestion that they be blessed by a loving God of perfection is what brings me into the debate.

If I were restricted to one in-your-face topographical feature for my belief in, for instance, the Genesis Deluge account I would rest on the well-known but inexplicable fact, for some, that there are vast planation surfaces found at several levels, generally three; all over the Earth. If you google 'planation surfaces' you will get an explanation of how a planation surface is formed; an easily understandable explanation of the conditions necessary for the production of such a formation; but NOT three, or more, planed surfaces on escalating (or descending) levels. The surface of the earth can be planed by glaciation, but such action leaves behind features like lateral and terminal moraine, drumlins, etc. However, the surfaces which cause problems are those which have been 'planed', or eroded, by fast flowing rock-bearing water. Left behind, and strewn across the surface of this plain as testimony, are roundish rocks and boulders of varying sizes.
The account of a great universal Flood, or Deluge, which surged backwards and forwards across the face of the Earth, scouring the land, repeatedly eroding and depositing layers of sediment, and the jumbled remains of forests, plants and animals, is recorded in the hundreds upon hundreds of remarkably similar stories in diverse tribes; handed down from the survivors. This tumultuous flooding went on for days, weeks, months - an unimaginable scenario. Compared to this catastrophe the floods in the Tigris and elsewhere, leaving a bit of gunge, are mere splashes. The original, probably low-lying, equatorial land was completely submerged. The 'fountains of the deep' - great reservoirs of underground water, surged up, with cataclysmic earthquakes belching forth lava to produce the huge sheets of basalt which cover great expanses without break all over the Earth. At some stage the earth began to be pushed up in places out of the water. Such a push would be followed by great surges of rock-laden torrents which would evenly abrade some of the mountaintops and rocks at each new lowered sea-level, cutting, with equal ease, across both hard and soft layers; resulting in a planation surface. Since planation surfaces (or planed surfaces) are found throughout the world at roughly three levels, this would indicate more than three further massive upthrusts of the land, with concomitant abrasion, scouring and deposition, caused by the violently disturbed and surging waters. The scouring rocks, some of immense size, left scattered over these great planation surfaces bear witness to the catastrophe.
And again the most important question; do you have the indwelling Holy Spirit which will lead you into all truth?
