False.
You are asking a question of 'is god there or not'.
No one has any facts in either direction to prove or disprove that. You can ONLY apply faith or belief in either direction.
If you and i go to meet Fred at Mall and we arrive and i say 'i believe Fred is here already' and you say 'i believe he is not', and neither of us has any data (we did not see or here him nor did he tell us he had arrived) then an agnostic view is the only logical one to hold. Being open to him being here or not yet arrived which you decide when you get further data.
In your example God is not different than an Alien. Simply believing they do or do not exist, in such a way you would say to someone 'Alien/God exists' or 'Alien/God does not exist' is nothing but a guess or belief.
If you want to live your life asserting baseless beliefs you cannot substantiate (in either direction) as if fact, go ahead. But understand the agnostic view is the only logical one.
