hauke , you should find some kind of avatar for yourself. It's not that hard. Just google something on the internet and then click on images.
My own current avatar represents my boonie hat that I wear while backpacking, hunting, and practically every day to keep the sun out of my eyes.
"God" is a concept from ancient religion and philosophy.
The ancient Greek philosophers starting with Hesiod and Thales were the first to try to separate "God" from "Philosophy".
The ancient Greek philosophers were doubtful of the validity of the Greek pantheon -- family of gods.
Although no one of them doubted that there was indeed one all-powerful Zeus, they could not justify the existence of any others.
The strongest argument in favor of several Gods comes from Hinduism. Why would a God choose to be alone? Most likely a God with godlike powers would choose to create another God or Goddess like himself for company.
Judaism and it's copycat Islam posit only One God. In Judaism He has many different names but the most recent and most revered is YHVH.
Islam calls their God "Allah" which is an Arabic word from ancient Egyptian and Babylonian meaning "powerful" same as the Hebrew/Babylonian word "EL" or "ELOHIM".
Christianity clearly has 3 Gods, morphed by creeds into One somehow.
The 3 Christian Gods are THEOS PATYR, IESOUS XRISTOS, and PNEUMA AGIA -- known to us in English as God The Father, the Lord Jesus Christ, and the Holy Spirit. In Latin these are called Patri, Fili, et Spiritu Sancti.
