Answer - Heat from the sun reaches to us by radiation.
Conduction, convection, and radiation are the three modes of heat transport that are known to exist. Heat is transferred through conduction when molecules in the medium collide. commonly seen in gases, liquids, and solids. According to conventional wisdom, the movement of the system's fluids is what causes the transfer of heat. commonly seen in fluids, such as liquids and gases.
Radiation is the process through which heat is transmitted across a medium in the form of electromagnetic radiation. We are aware that a vacuum exists in space and that electromagnetic radiation can travel through one. Thus, it is evident that radiation is the method by which the heat of the sun reaches the earth.
