Because they don't have enough energy to be noticed? If I understand right, they are not energized enough to ecxite electrons?

Radio waves are a type of electromagnetic radiation that are generated when an electric current oscillates back and forth. This oscillation creates a magnetic field, which in turn produces an electric field. These electric and magnetic fields travel together, forming a wave that can travel through space and carry information, such as sound or data.
Radio waves have a very low frequency and long wavelength, which means they have a very low energy level. This low energy level is not enough to stimulate the nerve cells in our skin, which are responsible for sensing touch and temperature. Therefore, we cannot physically feel radio waves.
The level of harm from radio waves depends on their frequency and intensity. Non-ionizing radio waves, such as those used for communication, do not have enough energy to cause damage to our cells. However, high levels of exposure to ionizing radio waves, such as those from x-rays and nuclear reactions, can be harmful to humans.
Radio waves have many practical applications in our daily lives. They are used for communication, such as in cell phones and radios, and for broadcasting, such as in television and satellite transmissions. They are also used in radar technology for navigation and in medical imaging devices, such as MRIs.
Radio waves can travel through most materials, including air, water, and some metals. However, certain materials, such as lead and thick concrete, can block or absorb radio waves. This is why we use lead shielding in certain medical procedures, such as x-rays, to protect the body from harmful radiation.
