Many tiny creature make their abode at the bottom of the sea when it is hard to sink a earthling there? mostly they would float at certain level .And also how those creature get their oxygen without fin or coming up for air?

The only reason why anything floats in water is because of density. If something is less dense than the water, it iwll float. If more dense, it will sink. If exactly the same, will be neutrally buoyant and neither sink or float. People, have internal gas bubbles which tends to mean a person floats. Dead people (who drown by filling the lungs with water) DO sink, but will rise later as bacteria produce gas as tissue decays (rots) which is trapped inside the body. If there is a way for the gas to escape, the body will stay on the bottom. Creatures living in water (non air breathers) transfer gases one of two ways, through gills or osmosis, neither of which produces bubbles, so they are neutrally buoyant and neither sink or float. By the way, fish have a buoyancy bladder which contains a small bubble of gas which makes them buoyant. By changing the size of this bladder (using muscles. Dead fish tend to float because they are no longer able to compress this bladder and they become less dense than the water around them, and float, belly up.) they can make themselves lighter than, neutral or heavier than the water around them. Water density is not uniform. As you descend, water gets more dense, not much, but enough so that the concept of neutral buoyancy becomes reality, so that a rigid body in water will float at some depth between the surface and the bottom, where it will exactly displace as much water as it weighs and neither sink any further nor rise above the neutral buoyancy point. Submarines do this all the time. They dive and then hold at 100 feet and trim (pump water in or out) to become neutrally buoyant at that depth and then they use the engines to drive down further. If they lose power, they will naturally rise back to near the surface to the point of neutral buoyancy.

There really are no Scriptures that emphatically state: "Charles Taze Russell is in heaven ruling beside the Lord". You're just not going to see it. However, keep in mind that just about every Christian denomination (Orthodox) believes when you die, you go to heaven to be with the Lord, so why couldn't this be true of Russell or anyone else? After the death of Charles Taze Russell, it was taught in The Watch Tower journal, that Russell was directing the affairs of the organization from heaven. While they have made many chnages to their doctrinal and organizational structures since Russell's death., they do teach that Russell, Rutherford and any of the spirit-begotten JW's who have died were resurrected in 1918 (the first resurrection) and have been reigning over the affairs of the earth with their Lord, Jesus. Can this be substaniated by scripture? No, no more than we can substantiate that any of our loved ones have gone to heaven when they died. I guess, we'll just have to wait and see ... of this one thing I am sure, their will be disappointment on both sides of the issues. That being said, whatever the Lord sees fit to give us, is still more than we deserve.

Well i think its either because we dont weigh enough :P or its just that there body is different and its just the way we lay you can sink to the bottom if you just put your arms by your side dont move them and go head first into the water

Bodies can and routinely do sink to the bottom of the ocean. Anything from "oceanic snow" (particles of organic matter), fish, and even whales sink to the bottom eventually.

1) dead bodies will sink. if microorganisms start digesting the carcass, they give off gases that are lighter than water (co2, methane, etc) this floats the body as it starts to decay.
2) in really deep water, there aren't enough microorganisms giving off gases to digest the organism and the carcass will not float.

Their density is different from ours, and most of the fish have to have swim bladders with varied amounts of gas if they wish to remain off the bottom with any ease.
