Other than first-hand knowledge, all evidence is circumstantial.
In response to all your detractors comments:
looking up words in English dictionaries for law jargon is a bad idea, you will get yourself thrown in the dock.

CIRCUMSTANTIAL EVIDENCE. The term in-
cludes all evidence of indirect nature. Milligan v.
State, 109 Fla. 219, 147 So. 260, 263.
It is direct evidence as to facts deposed to but indirect as
to the factum probandum, Brown v. State, 126 Tex.Cr.R.
449, 72 S.W.2d 269, 270; evidence of facts or circumstances
from which the existence or nonexistence of fact in issue
may be inferred. People v. Steele, 37 N.Y.S.2d 199, 200,
179 Misc. 587; Wolff v. Employers Fire Ins. Co., 282 Ky.
824, 140 S.W.2d 640, 645, 130 A.L.R. 682; Scott v. State,
57 Ga.App. 489, 195 S.E. 923, 924; inferences drawn from
facts proved, Hatfield v. Levy Bros., 18 Ca1.2d 798, 117 P.
2d 841, 845; preponderance of probabilities, Hercules Pow-
der Co., v. Nieratko, 113 N.J.L. 188, 173 A. 606, 610; pro-
cess of decision by which court or jury may reason from
circumstances known or proved, to establish by inference
the principal fact, People v. Taddio, 292 N.Y. 488, 55 N.E.
2d 749, 750.
It means that existence of principal facts is only inferred
from circumstances. Twin City Fire Ins. Co. v. Lonas, 255
Ky. 717, 75 S.W.2d 348, 350.
When the existence of the principal fact is deduced from
evidentiary by a process of probable reasoning, the evi-
dence and proof are said to be presumptive. Best, Pres.
246; Id. 12. All presumptive evidence is circumstantial be-
cause necessarily derived from or made up of circum-
stances, but all circumstantial evidence is not presumptive.
Burrill.
The proof of various facts or circumstances which usual-
ly attend the main fact in dispute, and therefore tend to
prove its existence, or to sustain, by their consistency, the
hypothesis claimed. Or as otherwise defined, it consists in
reasoning from facts which are known or proved to es-
tablish such as are conjectured to exist.
INDIRECT EVIDENCE. Is that which only tends
to establish the issue by proof of various facts
sustaining by their consistency the hypothesis
claimed. It consists of both inferences and pre-
sumptions. Lake County v. Neilon, 44 Or. 14, 74
P. 212, 214.
