The processes of life and the processes of machines can be compared and similarities can be seen, but conflating the two is a very bad move to make.
A machine is something created by an intelligent, living, creature. To date, the only machines we know have are created by man. Life, is not created by anything intelligent, and so cannot be called a machine. The fact that there are similarities is that we often copy living processes in our machine designs. There is no grand conspiracy to hide the designed aspects of life, there are no willfully blinded people who cannot see the overwhelming evidence you profess to have, there is no there there.
Machines are not always made by intelligent creators. A simple lever is a machine, yet can be made when a tree falls onto an uneven surface. We have evidence of naturally-occurring nuclear reactors in the Earth's past that were certainly not made by any intelligent being.
