Sounds like Erich von Daniken's "
Chariots of the Gods"
https://en.wikipedia.org/wiki/Chariots_of_the_Gods%3F . I've read it; among other things he believes that the Ark of the Covenant was a radio given to Moses by aliens to send him advice and commands.
I am agnostic and scientifically minded, and one aspect of the scientific mind is that it should be an open one and not form firm opinions about things that cannot be proved or disproved by experiment. God's existence (or that of any other gods of the biblical type, rather than of the shoulder-rubbing Greek style for example) can be neither proved or disproved in the scientific way. Certainly the God as styled by some religious sects can be dismissed as nonsense, because people have their own agendas and claim God is on their side, and shape Him accordingly.
There are many things beyond science, either for now or for always. For example science cannot at present explain time, despite the fact we take it for granted (a layman would ask why it even needs to be explained) and can use it in technical calculations like dynamics; we don't know how time came to be manufactured, along with matter, by the Big Bang and whether it existed before then. The explanation of how the four fundamental forces* of nature relate to each other, and to time, is still awaited (currently referred to a bit jokingly as "
The Theory of Everything"); Stephen Hawking spent a lot of time trying to derive it and concluded that it could not be done - ie no matter how much we understood each of those entities individually, we could not link them all to each other

We are like toddlers born and brought up in a windowless room with plenty of bricks and sand to play with. We are bright kids and get to know a great deal about the geometry of bricks and the properties of sand, but we have no idea where they came from or what is outside the room.
