authorized to administer oaths, and officially certified to by the officer under his seal of office.” Tex. Gov’t Code § 312.011(1). That definition contains the “statutory requirements” for an affidavit. Ford Motor Co. v. Leggat, 904 S.W.2d 643, 645 (Tex.1995). When an affidavit meets the Government Code’s requirements, it may be presented as summary judgment evidence if it complies with Texas Rule of Civil Procedure ledaCf). See Tex.R. Civ. P. 166a(f); Life Ins. Co. of Va. v. Gar-Dal, Inc., 570 S.W.2d 378, 380 (Tex.1978) (stating that Rule 166a(f) “sets forth the procedure for presenting summary judgment evidence by affidavit”). When a written statement does not meet this basic definition, however, it is “no affidavit at all.” Hardy v. Beaty, 84 Tex. 562, 19 S.W. 778, 779 (1892) (<HOLDING>); see also Anderson v. Cochran, 93 Tex. 583, 57
