You have no idea how far away from being able to clone humans they are. They have enough difficulty cloning a single cell. Even if money had been poured into for fifty years, it is unlikely that they would be anywhere near.
Most of the conspiracy theorists forget one thing when it comes to science. If there were all these underground labs funded by governments and industrialists, that were miles ahead in their chosen fields, whilst they might be top secret and not want anyone to know what they are doing, they would discover things on the way to their goal, which they would patent the technology on then release to the public and make more money to fund their work.
These things don't happen because these labs, are not that far ahead of any other labs. Most R&D labs in a certain field are in roughly the same position, but trying different methods to achieve the same goal, the one's that succeed, make money from that success and then everyone carries on with the next thing.
