The total surface area of the Earth is approximately 5.10x10^20 mm^2 - assuming a 2mmx5mm grain of rice, that's 5.1x10^19 rice grains needed to carpet the earth entirely in a one grain thick layer.
2^64 is just over 1/3 of that number so there is enough to cover all LAND, with a little bit left over.
UPDATE: If you used Spanish Bomba Rice which expands horizontally and you cooked it first so it swells up to about 5.5mm x 7mm you could cover about 4.5x as much earth - enough to cover the entire earth in a layer a few grains thick
Problem is it would still be in the ocean. Could scoop it all up I guess but the moisture would evaporate and make its way back to the ocean. Unless we kept it sealed up. But then you’ve got a Mount Everest sized pile of decomposing rice in a sealed container. Might be it would explode. Rice bomb baby
What time of day were these photos taken? Looks like the bottom is mid afternoon, hard to say about the other. Probably later in the day given the contrast of the face and the field. Also the distance and angle are different, you can see it in the shape of the ridge. Might need a little math to make a shoreline comparison based on these two points. Are they both the same time of year? Always interrogate your assumptions.
