Please do not believe in Allah only if in your heart you HONESTLY have a better model of creator than Allah of Islam. It is acceptable to Allah. Allah will turn to you even if you reject Him and are seeking something Better. He will continuously help you recognize him because he Loves you and Wants to Save you. He created you, You represent him, and he will always help you if you are honestly seeking truth.
Allah loves us 70 Times more than our mother does.
