The most obvious sign of fire cause is:

The initiating energy—the ignition source—that started the fire is the most direct clue to what caused it. When investigators examine the origin, finding a credible ignition source there (like a heater, electrical device, or open flame) ties the event to a specific starting point and mechanism, making it the strongest indicator of the fire’s cause. Other signs describe what happened after ignition—how much damage occurred, the presence of unburned debris, or the smoke’s appearance—but they don’t pinpoint what started the fire. So zeroing in on the ignition source at the origin provides the clearest link to the cause.
