Are all religions cults?

• The laws of thermodynamics.
  
• What science is finding out about the very nature of intelligence contradicts the idea of an omniscient and eternal god.
  
• Speed of light is a constant and nothing can go faster than it.
  
• There is no physical mechanism for your god to sense and interact with the world.
  

I don't see where any of that contradicts theism.

The law of thermodynamics is often used in support of it.

Wrongly though. The argument goes that life violates the second law but it does not because order is created locally at the cost of an increase of global entropy.

1) The second law of Thermodynamics means that global entropy must always increase. This means that your god cannot be eternal. What's his power source?
2) An omniscient god cannot be intelligent (plus all forms of intelligence are self organising systems subject to the laws of thermodynamics)
3) Where is your god and how far away is he? The speed of light means latency is an issue.
4) Scientists have found no mechanisms by which your god can sense and interact with the world. But you say he does, and to a significant degree as well. If this was true, the physical mechanisms would have been discovered by now (and also exploited).
